    I want to know wether i have a catalyst or transmission problem or something else?
    my car sat for 15 months. I just fired it back up after changing the fuel pump & filter, oil change as well as coolant flush and replaced the belt. i drove it around the block. It smelled like gun powder . i then took it to wash the engine and under carriage due to ...

      Even if your check engine light is off, you should still diagnose your vehicle with a scan tool/code reader. It is the only way to verify if there's a stored troublecode in your vehicle and if all your electrical connectors and controls are still functioning well.

      Thanks for the advice. I'm definitely doing that.

      Here's how to remove the shift cable in your vehicle

      First remove the shift knob, locknut, console, bezel assembly, control cable clip and cable retaining pin.

      And then disengage the rubber grommet from the floor pan by pushing it into the engine compartment. Raise the car and safely support it on jackstands.

      Remove the retaining nut and control cable assembly from the transaxle lever. Remove the control cable bracket bolts. Pull the cable through the floor.

    When I accelerate I can hear and feel something grinding from the front left. What is causing this?
    The car is slower because of this.

      it could be brakes or wheel bearings from what you have said either one. If you have a bad caliper it can eat a set of pads in less than a month

      There are several components that make up the engine starter circiut, careful troubleshooting of all the components is often necessary in determining the faulty component. The battery, battery cables, starter, starter solenoid, ignition switch, neutural safety switch, and ECU all play a role in the starting circuit. Of these, the ignition switch and ECU are in the passenger cabin, sometimes located under the dash. The neutural safety switch location varies, although it is normally part of the transmission or shift linkage. Can you be more specific with the sting problem? Does it make any noise when you turn the key to start? Have you had issues with the battery recently?

      * Engine Cranks but won’t Start

      Probable Causes:

      * Fuel Pump (P0230 to P0233)
      * PCM (P0600 to P0606)
      * Crank Sensor (P0355 to P0399)
      * Fuel Pressure (P0190 to P0194)

      Chances are the Check Engine Light is not on, but you may find any of the following codes:

      * P0230 to P0233 Fuel Pump codes
      * P0600 to P0606 PCM related codes
      * P0335 to P0339 Crank Sensor codes
      * P0190 to P0194 Fuel Pressure Sensor codes

      No spark due to a bad crank position sensor, a faulty ignition module or PCM, a problem in the ignition circuit (ignition switch, antitheft system, wiring, etc.), a faulty park/neutral safety switch, a bad ignition coil (only on engines with a single coil ignition), or wet plugs or plug wires (did it rain last night, did you just wash the engine?)

      A less common cause is a worn starter that draws so many amps while cranking the engine that there’s not enough juice left to adequately power the ignition system and fuel injectors. Contributing factors might be a weak battery and/or loose or corroded battery cables.

      No fuel because of a dead fuel pump, bad fuel pump relay, blown fuel pump fuse, plugged fuel filter or line, or failed PCM injector driver circuit or injector power supply relay. Or, the fuel tank might be empty (don’t believe what the gauge is telling you), or the fuel tank might contain contaminated fuel (water or too much alcohol) or the wrong type of fuel (whoops, somebody put in diesel instead of gasoline).

      No compression because the timing belt or chain is broken, the timing belt or chain is loose and jumped out of time, or the overhead camshaft has snapped. A powerful scantool like AutoTap Express DIY can help isolate the root cause by capturing this information.

      The first step is to determine if it’s a spark, fuel, or compression problem. Here’s a quick way to find out which of the three is missing. Remove a plug wire, insert a Phillips screwdriver or spare plug piece of bare wire into the plug wire boot and place the end near the engine block (do not hold the plug wire while cranking the engine unless you want a shocking experience). If there’s a spark when the engine is cranked, it has ignition. The problem is either fuel or compression. If the engine has an overhead cam with a timing belt, loosen the cover over the timing belt and check the belt. If the belt is okay, the problem is no fuel. Listen for the electric fuel pump in the fuel tank to make a buzzing noise when the ignition is turned on (you may have to open the gas cap to hear it). You won’t hear anything if the pump has died. Diagnostics can now be focused on the fuel pump circuit to determine if the pump, relay or wiring is causing the no start. If the relay has voltage but the pump isn’t running, you’ll probably have to drop the fuel tank to check the wiring connector at the pump. If the problem is no spark, anything in the ignition circuit that creates the spark may be at fault. Use your AutoTap Express DIY to look for an RPM signal from the Crankshaft Position sensor while cranking the engine. A bad Crankshaft Position sensor is a common cause of no starts. The signal from this sensor goes to the PCM or ignition module that switches the ignition coil(s) on and off. If you have an RPM signal, a bad ignition module or PCM may not be switching the coil(s) on and off. Using a voltmeter, check for voltage at the coils with the key on and while cranking the engine. The voltage should be switching on and off. In ignition systems with a single coil and distributor, a bad coil or a cracked distributor cap or rotor can prevent the spark plugs from firing. On multi-coil, distributorless ignition systems and coil-on-plug systems; one coil failure may cause an engine to misfire, but it won't prevent it from starting. What’s causing the no-start? All engines require three things to start and run: spark, fuel and compression. If any one of these isn’t there, you aren’t going anywhere.

    What is wrong with my transmission?
    It shudders (shakes) really bad when it shifts at low rpms and when I come to a stop and go after traveling at speed it starts out in second gear until I give it decent throttle to down shift into first.

    The cruise control does not appear to work. It does not engage or function when the button is pressed. Does anyone hav
    Does anyone have any ideas where I should start to track down the problem if it would just be a simple fix or need a major overhaul?

    What are your thoughts on a transmission fluid flush? Have 122,000 miles on vehicle, owned it 2yrs
    recently, sticks, slowly goes from 2nd to 3rd gear, when taking off. once going 45 or faster runs smooth.

      Yes do it like NOW.

      Automatic trannys are reliant on clean good oil.

      Keep in mind new fluid could dissolve varnish and sludge which is helping to keep seals from leaking, especially if you have never changed fluid.

      I agree with Bill however with one caveat; I have a TransTech II transmission fluid exchange machine and I use it often. I only change the oil if the oil in the unit is still RED in color. If it is black or brown I do not touch it. Had a couple of units take a dump not long (within a few months or less) after changing out badly discolored oil.

      Thanks for the info. I am having it checked today at a local transmission place a buddy of mine works at. I am hoping its not discolored, so I can go ahead and change the oil. If its I looking at a new transmission? Is it worth it to get a new transmission? 98....122,000miles? Love the car....not sure if its worth to put that money into it.
      2/18/2012 Spoon Sports
      My take on it is, if you love the car, spend for it. THats why i still have my 93 Civic with me, shes my wife.

      Besides, with a new tranny, its gonna last for another several thousands of miles assuming you know how to maintain your new tranny.
