SYMPTOM/CONDITION:
An intermittent rough idle may occur during cold engine operation, within 3 minutes after engine start up, in rainy weather and temperatures of approximately 30° to 50°F.
PARTS REQUIRED:
Quantity Part Number Part Name 1 4288298 Idle Air Control Motor (IAC) REPAIR PROCEDURE:

1. Remove A/C motor.
2. Install new IAC motor (P/N 4288298) and rubber O-ring, torque to 2 Nm (17 in. lbs).

CAUTION: The rubber o-ring must be installed with the IAC motor for proper operation.

I would also recommend doing a fuel pressure test to see if it loses fuel pressure overnight.

could be low on water or water pump could be week or your heater core could have a blockage.

Hi.

Replace fuel filter, spark plugs and air filter.

Be sure that fuel is getting to the injectors. Fuel pressure can be read by using a fuel gauge ( like this: Fuel Pump Vacuum & Pressure Tester) in the apposite port on the fuel rail.

If there is a problem with fuel, check pump, pressure regulator and lines. Relays.

Check if there is spark. A way to do this is by unplugging one of the high voltage wires that go to the spark plug and listening to the difference in engine sound and performance. If the spark plug connector is placed near to the engine block (which is grounded), you will also see the spark.

If there is no spark, then ignition coil and rotor must be checked.

Check if there is voltage to injectors. If there is no power to injectors, problem is PCM or wiring.

Check the MAF sensor and the vacuum system. A defective sensor or a vacuum leak may result in wrong mixture and the engine may not start.

Common failure causing no start in this car is either fuel pump or crankshaft position sensor. I think problem is one of the two.Check both of them properly.

It may be needing a tune up and maybe a new battery ... See your mechanic concerning these two items.

Thanks fo ryour visit today.

It's normal for that to happen.It uses AC system to help remove condensation for defrost. You'll notice it doesn't happen on heat, only defrost. AC may be slightly low on freon causing it to cycle on & off more frequently.

n your trunk pull back the carpet should be eaither on the back by the tailights or up fron more by the wheel wells

NO! it is under pressure(safety first my friend). The pressure has to be there for the fuel pump. anyone that says yes, is a fool. You want no leaks. You can order a new line from the dealership( check your auto parts store first). Much safer and will be the right part. Please, don't do that.

passenger side under back seat floor under in front of tire is the fuel filter location fuel line 15/16 use EFI fuel line for best results

Hi,

A good place to start would be to check the fluid(if it's an automatic transmission).

Usually on tag on underside of hood as well. If no luck, go to ( http://www.decodethis.com ) and it will give you a complete rundown on vehicle, when you enter you V.I.N. #

Heater resister network is bad .

This can be the transmission mode switch (on the side of the trans), or worn clutches or bands. There can also be trash in the valve body or a stuck solenoid. Your best bet is to bring it to a transmission shop for the free diagnosis. Good luck!

Thanks for the vote.

you should have a belt tensioner that you can put a box wrench on and pull back on to relieave the tension on the belt . Pull the belt off the closest pulley and enjoy , dont forget the route it gos back on though !!! take a picture if need be!!!

check fuses first if its good the fuse trace wires to find the short

spend 20 dollars and get yourself a repair manual on ebay before you take a wrench to it. it is pre 90s passenger airbag so you should be able to do it yourself with enough time. do a search on youtube, lots of car videos there.
