hey whats up guys,

Or i did alot of searching and I have alot of ideas but no solid answer becuase im not sure if people have the same problem that I have. here is the problem

When I start up the car the idel is fine. a little high but not bad plus it is getting colder. so after i drive the car for a while every time i stop the cars RPM's pules. the go up and gown about 1,000 RMP's. the warmer the engine gets the more it happens. when the engine is cold it dosent happen. I have not had a diagnostic check on the car yet. it is expensive to have it down so if any one has had this problem and has fixed it please help me out. the car is using up alot of gas. my car has 170,000 miles on it.
thanks alot guys for the input.

Alos check out my other page where I have a bunch of parts for sale if u need interior stuff.

You can do a self diagnostic test on it yourself. Just a thought. Got any copper wire?

What kind of mileage are you getting?

this sounds like an IAC or vacuum leak. 1st, pull some engine codes.

The IAC is attached to the bottom of the throttle body. If there are bubbles in your coolant this can mess up the IAC and cause a searching idle, but 1000rpms...I doubt.

I am amazed at how people can answer questions yet they do not realize the the relevant information about the car.

1. You have a 1996 Mx6, which implies OBDII. Which requires a reader, NOT a copper wire. You CANNOT pull the codes yourself, if you try you might risk frying the ECU and you still won't get any code, because it is a computer design.

2. Do you have the V6 or the I4. That can make a huge difference seeing how the V6 throttle system and I4 is completely diffrent. The V6 relies on a TPS sensor that can be controlled and also has coolant pumped into the TB. The I4 on the other hand has no such TPS since it runs on a MAF system.

Either way you need to take it to someone that has a code puller for OBDII cars or you can buy your own for around $150.

Doesn't autozone pull codes for free? Or is that only for ODB-1?
