    Why will my car periodically stall while driving ?
    Occurs mostly when I have a full tank of gas. Sometimes will not turn over after it stalls. Just began happening recently.

      First step - have the stored fault codes or check engine light scanned - for free - at any local auto parts store; Advance Auto, Auto Zone, NAPA. Then, post a reply as 'add answer' with the specific code for more assistance. There may be a fault code stored in the OBD memory which may not be displayed as a check engine light.

      Possible Causes of Engine Hesitation or Stumble:

      Dirty fuel injectors (cleaning the injectors often fixes this)
      Dirty air filter (change filter)
      Dirty / clogged fuel filter (change filter)
      Bad MAP (manifold absolute pressure) sensor
      Bad TPS (throttle position) sensor
      Bad or dirty MAF (mass airflow) sensor
      Low fuel pressure (leaky fuel pressure regulator or weak fuel pump)
      Vacuum leaks (intake manifold, vacuum hoses, throttle body, EGR valve)
      Bad gasoline (fuel contaminated with water or too much alcohol)

      Sometimes, what feels like a hesitation is actually ignition misfire rather than lean misfire. The causes of ignition misfire may include:

      Dirty or worn spark plugs
      Bad plug wires
      Weak ignition coil
      Wet plug wires

      came across this a few times in my shop. 2 common problems. #1 - Check the "vapor canister purge valve". The ones I found were stuck open. During a cold start, the engine would suck the gas fumes in along with air so the engine would start easily. But once started, there is too much air and the engine runs lean. Feathered to go, once over 30mph, the purge valve normally opens and the engine runs great with no problems on restarts. #2 - The map sensor and/or the vacuum source. Remove the 10mm bolt holding the MAP on the intake and check it for sludge build-up and the condition of the 2 "O" rings. Replace if necc.

    Why does my Cruise Control only work once per trip?
    This has been happening for some time now: I get on the highway, get up to speed, and turn on the cruise control. It works perfect until I run into traffic and have to turn off cruise control. When I try to reengage cruise control, it won't turn back on. Cruise ...

      First question - how does the engine run / operate at idle speed without the AC? Does the engine start and run OK with the AC off?

      If yes, then the issue may be related to a faulty radiator fan switch - at low speeds the fan runs to circulate cooling air in the front of the engine across the radiator.

      If the cooling fan does not come on at any speed, you would have reported about overheating at stoplights, rather than a stalling problem. I believe the fan’s low speed is no longer working. With the a/c turned on, the lack of air circulation over the condenser at stoplights causes the system’s high-side pressure to rise to a higher-than-normal level. This puts an additional load on the a/c compressor, which in turn causes the engine to work harder. The extra load on the PT Cruiser’s 2.4L 4-cylinder engine causes its idle speed to drop to a lower-than-normal level. If the condition continues long enough, the engine might even stall. Surging and hesitation at lower road speeds could also be a problem.

      Are you also experiencing the a/c performance affected at the same time? Can you verify the a/c high-side pressure at idle with a set of pressure gauges?

      Cooling fan operation can be controlled by a scan tool actuator test. Try actuating both fan speeds this way. If only the high fan speed works, you can verify that the low-speed motor windings have failed by checking for power and ground at the fan connector while the scan tool is commanding low-speed operation. You can also provide power and ground with jumper wires if you’d prefer to activate the motor manually. Ground is in the center of the three-terminal connector, with the high-speed and low-speed power feeds on either side of it. Check a wiring diagram to verify the terminal positions.

      If the low-speed and high-speed cooling fan windings check good but they’re not receiving power and ground from the computer, begin checking upstream. Corrosion at the cooling fan relay terminals in the relay box is a good place to start. Once again, try activating the cooling fan circuit with the scan tool actuator test. If the “fan on” command is arriving from the computer but doesn’t make it to the cooling fan, you probably have some corroded fan relay terminals to clean up or replace.

    Hesitate sometimes when accelerator is pressed
    my 97 sebring runs fine most of the time but at times when i make a complete stop and then press the accelerator to go it hesitates and when i release the accelerator and press slowly to go it runs without hesitation what could the problem be?

    Engine makes ticking noise after overheating
    My engine in my 2000 Chrysler 300 recently overheated due to overdue oil change. It has 246770 km on it. Now when I tried to start it again after putting new oil in it, it makes a ticking noise. And it ends up stalling after a few minutes of it just idling and ...

      Make sure the oil filter has been changed, look at the oil, does it look and smell new or black and stinky ? BTW, Have u checked the oil level after each time it runs ? Do that! could be something easy like the tailpipe stuffed with penis's !

    Bubbling noise when ideling but does heat up
    have repaired several raditor hoses etc. items but starts bubbling noise when at stop lite and at drive thru

      Pop hood and try to locate the location of the bubbling. You may find that the bubbling is the radiator overflow tank which should have coolant in it and the bubbling may be from there. In the past this was caused by a bad head gasket allowing exhaust gasses to pressurize the coolant system with exhaust gas and it then bubbles out through small hose to this tank. You can have a bad head gasket and no overheat condition. Had it been a cracked head or cracked block you'd find yellowish or brownish muck in the oil, most commonly found under oil cap but also on dip stick etc.

      I may have a similar problem on my 2013 Acura TL. It seems to happen a couple of minutes after startup and when the transmission is in drive with the brake on, such as at a traffic light or drive-trough. It sounds like a bubbling or popping sound (sort of like a percolator) coming from the dash near the steering wheel. On my car it goes away after the car is fully warmed up. I took it to the dealer a couple of times. They insisted there was nothing wrong, and suggested it was from the transmission cooler which is located under the floor near the driver's feet.. Apparently when the transmission oil temperature and pressure first reaches the required condition, it is pumped into the cooler on top of the transmission and causes the bubbling noise for a few minutes before reaching the right temperature. I don't know if I totally agree with this explanation. I can't find any support for it elsewhere on the internet, and no other car that I've ever driven, including other Acuras, ever exhibited this problem. However in trying to troubleshoot the problem on my own, I did notice that the bubbling noise stops if I shift the transmission into neutral. Another possible solution which I found on the internet, but with a different make of vehicle (Land Rover I think), suggested it was from the brake booster?, the big round thing under the hood on the firewall near the steering wheel. I don't know if this helps with your problem or just makes it more crazy. If anyone can provide conclusive evidence on the cause and fix to this problem, please email me (caperfamily@gmail.com).

      P1391 = CMP or CKP Signal Intermittent Condition

      - Timing belt or chain stretched or jumped
      - Faulty Camshaft Position (CMP) Sensor
      - Camshaft Position (CMP) Sensor harness is open or shorted
      - Camshaft Position (CMP) Sensor circuit poor electrical connection.

      Possibilities include those listed above, as well as harness problems. Try wiggling wires, but I'd suggest looking at the harness in the immediate area where they plug into the top-left area of the engine. Upturned valve cover edges, protruding bolt heads and just plain metal everywhere may have worn some insulation off in a particular place. Inspect the harness carefully anywhere it will normally come into contact with metal... whether it's sharp edged or not.

    Engine stalls when i accelerate quickly
    if it's in park and i accelerate it runs perfectly smooth. if its in drive and i try to accelerate quickly it sort of feels like it stalls a little. if i accelerate slowly it runs perfectly well. It's not the transmission because i had it checked. what can it be?

      Firing order is 123456 for your vehicle. Spark plugs attach to distributor cap as follows:

      When looking at the distributor from the front of the engine, and starting at the nine o'clock position, going clockwise:
      - #6, #2, #4, #5, #3, #1.

      The number one cylinder on your vehicle is on the engine's left side. Meaning that if you were to orient yourself in the same position as the engine, it would be your left. The distributor is at the front of the engine.

      Romove the number one cylinder spark plug. Remove distributor cap. Using a breaker bar and the correct size socket, rotate the crankshaft clockwise (when looking at the crankshaft from front of engine). Turn the crankshaft clockwise to set the number 1 cylinder at the compression stroke to top dead center. You will be able to see, with a flashlight, if the piston is at the top. If you cannot see the piston, insert a long enough screwdriver to feel how far the piston is from the top. DO NOT drop the screwdriver into the cylinder. If you are unsure as to if the cylinder is on it's compression stroke or exhaust stroke, refer to the timing marks located on the harmonic balancer. When the timing mark on the harmonic balancer aligns with the mark on the timing cover/ engine block, the number one cylinder is located at the top of its compression stroke. Now , you can refer to the distributor to determine which way the rotor is to be pointing.
