2/17/2013 HouseCallAutoFirst thing is plug in a scan tool / code reader and see if the tool can establish communication with the vehicle ECM. If it cannot communicate then this most likely either has a bad Electronic Gas Injection (EGI) Main Relay or it has a bad Engine Control Module (ECM) . If it can communicate then see what fault codes may be stored and update the post with the codes.
bjc_jo - 2002 Kia Sedona - Engine - 2/15/2013i had to put the brain box and all the wiring redone in my van it has 105,570 miles on it i'm now having problems with the crank shaft the bolt that runs the motor is stripped out what is the crank shaft made out of and can it be rethreaded to fix? are any of these ...
cherylnappier - 2002 Kia Optima - Engine - 2/14/2013If gas is tried to be put in with pump, it vomits the gas back out. Gas can be put in with a small gas can no problem.

2/13/2013 HouseCallAutoRarely do mechanics do a rebuild on a clients car engine. Those days are almost gone. It's better to just buy a remanufactured engine and have the shop install it but expect $5000 bill with a 3 year unlimited mileage warranty. Only way to get that down to a number like 2500 to 3000 is to buy a used engine but there is no warranty with a used engine. Nothing wrong with fixing your 08 Optima but obviously you have to really want to keep your same car as many people become emotionally not ready to change out cars.
Agustin Nieves - 1996 Kia Sephia - Engine - 2/13/2013Ok, The car doesn't start. I have new spark plug and spark cables. The crank shaft sensor is new, the ignition too. The battery works fine and the battery terminals are new.The starter works too. The car is in time and the timing belt is ok. The fuel pump works. I ...

lindasmith32 - 2003 Kia Optima - Engine - 2/3/2013a new battery has been installed , a new timming belt, a crank sensor installed , oil changed and it will run for a day or so and then it won;t start , I have been stranded three times in the last 4 weeks , it only has 48,700 miles on it
tpeacher68 - 2007 Kia Sportage - Engine - 2/2/2013I have 80,000 miles on my Kia but for the last 2 days when I take off it feels like it is not getting enough gas to keep it from sputtering at first. Then it stops and runs fine. It does not do it if I begin moving very slowly.
2/2/2013 JimmFirst step - have the check engine light or stored fault codes scanned - for free - at any local auto parts store; Advance Auto, Auto Zone, NAPA. Then, post a reply as 'add answer' with the specific fault code for more assistance.
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
rangerdad111398 - 2004 Kia Sorento - Engine - 2/1/2013battery and the brake idiot lights are on, then afeter a while shut off, then come back on. hesitated to start, so replaced the battery..started one time, now wont start again
cozmaclaudia13 - 2006 Kia Spectra - Engine - 1/25/2013-it is turning over, has spark, getting fuel, and still does not start -I put starting fluid in the air filter and the car starts but dies immediately.
mike - 2005 Kia Optima - Engine - 1/25/2013Rough idle and tachometer fluctuates or drops to zero.
1/25/2013 JimmP0320 = Ignition/Distributor Engine Speed Input Circuit Malfunction
First check the 20 amp ECU fuse in the under hood fuse box. Also check the O2 sensor fuses. If good, next check for battery voltage on the tan/black wires going to the coils while cranking. If good, check for ground of 0.05 volts on the black wires going to coils while cranking. If either is missing, check O2 wires for chafing or rub thru on heatshields or other objects under vehicle. Verify the O2 sensors operation is correct, if so - suspect the ignition failure sensor.
mike - 2005 Kia Optima - Engine - 1/18/2013Tachometer fluctuates but no rough idle
1/18/2013 JimmP0300 = Random/Multiple Cylinder Misfire Detected
A P0300 diagnostic code indicates a random or multiple misfire. If the last digit is a number other than zero, it corresponds to the cylinder number that is misfiring. A P0302 code, for example, would tell you cylinder number two is misfiring. Unfortunately, a P0300 doesn't tell you specifically which cylinder(s) is/are mis-firing, nor why.
A code P0300 may mean that one or more of the following has happened:
•Faulty spark plugs or wires
•Faulty coil (pack)
•Faulty oxygen sensor(s)
•Faulty fuel injector(s)
•Burned exhaust valve
•Faulty catalytic converter(s)
•Stuck/blocked EGR valve / passages
•Faulty camshaft position sensor
If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.
If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.
yertaj1028 - 1998 Kia Sportage - Engine - 1/14/2013Car has been idle and park for few weeks before replacing the battery.
EdgeAle - 2002 Kia Rio - Engine - 1/12/2013Cleared a code (for very small evap system leak) back in Dec. Three monitors are still "not ready/incomplete". I have been told that the other two won't finish until after the O2 monitor does.
