Caravan rough idle

I would stop going to that auto zone to start with, then I would clean the throttle body that your vehicle does have before you do anything else!!

Thanks Gentlemen for kind replies (applies to the next poster too).

I have good mechanical aptitude, therefore I am confident I can clean it myself, so please just tell me its approx location. Like is it right where intake air hose connects to EFI housing with a "T" clamp?

Do I need any seals or gaskets to replace once I take it apart? I promise I won't buy it from AutoZone!

Thanks again. Mike

The EFI housing that you are refering to is a intake plenum. Yes the thing that the air hose attached is your throttle body. Remove that and get your self some brake parts cleaner and give it hell. I use a good toothbrush to scrub it out also, but make sure not to use something that is old and will lose bristles. Remove the AIS motor and clean the piston seat also. Gunk gets in there and wont let that seat properly. You will need a gasket. Yours will likely break and if it doesn't replace it any way. Go to your dealer and get the gasket. They should have the right one and its only a couple of bucks. Autozone is only good for oil and chemicals. The brake parts cleaner they have is wonderful.

Thanks. Do I need to bleed fuel pressure? Or I shouldn't mess with the fuel side of it?

Mike

It has nothing to do with fuel. It is the incoming air going into the engine.....I would suggest using a throttle body cleaner over brake cleaner.

Thanks, will do!
