    if you are correct, will it dry out on its own? or do I a repair?

  • Connie Cannavan Jan 06, 2013

    We took the kia to our mechanic. It had water in the #1 cylinder. they dried it all out, then replaced the plugs and wires. car was a bit over due for a tune up, so now the car runs better than before. Thanks for your help!

Sound like you got water somewhere you didnt need to, If this model has a distributor but if it does make sure it is dry inside and no filing going (corrison).

    there is no distributor on this model. My son covered parts so they would get wet, but when he made a right turn I think the water ran onto those parts.

Get the check engine code to guide you, you probably got one of the coil packs wet and its causing a miss fire

SOURCE: 2003 kia spectra check engine code p0604

I have bad news for you
p0604 is a transmission control module

check the connection at the transmission control module if there are no connection issues than you will need to replace the transmission controll module "tcm" there is no other test for that code.

good luck

I have a 92 Isuzu pickup with a L4 2.3L. that recently started idling rough and idles up and down when stopped. It has 111,000 miles on it. It runs fine once I take off.


no check engine lite? if not pull the air intake tube and look for a dirty throttle body. the idle air valve may be unable to seat so it is searching and needs cleaning. use a carb cleaner that is safe for throttle plates. and use your finger to rub around the plate to clean the gunk off

Car back fires in the engine and wont stay running after a few tries it will but stalls then turn key and runs ok untill its cold again?anyone have a clue??? plugs have been changed and check engine light...


Most probably the vac is leaked. Spray some carb cleaner at the intake (while the engine is running) and see if the sound changes after addinh the carb cleaner. If it still misfires add some more carb cleaner to clean the nozzles of the MPFI system. it should help.......sodeep

2002 kia rio stalls when coming to a stop if the gas is not applied


My personnel fix for this.

Here are some of the causes of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

ROugh idle


there are 2 things that usually cause this, one is a dirty intake idle control valve and the other is hard engine mounts, I would say that both most likely apply to your car. try cleaning the intake with the following procedure from Ford.

2003 Kia Spectra Loss of power during exceleration


Hi,
The air cleaner mighty be clogged causing insufficient air supply. That is why it runs fine on idle because less air is needed and when the engine demands for more air, there isn't enough.

My 2003 kia spectra stalls


Hi,
It might have a partially blocked fuel line or ait intake supply.
  • Try to check your fuel filter.
  • The seive on the fuel pump.
  • The fuel injectors might be dirty.
  • The air cleaner might be clogged
or the fuel sensor might be malfunctioning.
Try to check the compression, it might be loosing compression when you demand the engine to move the vehicle.
