The EGR valve is held in with two bolts just like the IAC vavle. If you're going to do an in depth cleaning you'll need to take both of them off.


The cleaning is pretty straight forward. Get yourself some carb / choke cleaner. I like berrymans b12 chemtool , its the best stuff I've ever seen. When you take them off you'll see wether they need cleaning or not, it will be obvious.

The opening that the EGR valve goes into has passages that lead to behind the throttle body.







Wow, fun day. I had a lot of trouble finding the gaskets. The dealer I called nope, 2 Autozones, 1 Napa...

I took off the TPS, IAC, throttle body and loosened the EGR. Cleaned them all off, the only one that looked bad was the throttle body.

Also replaced the fuel filter.

I will experiment over the next few days with the unhooking a sensor and seeing what's not working...


Thanks for the suggestions.



Well, so far so good. Since finishing up the cleaning work on Saturday night, I have driven the car 3 times. Once on Sunday 25 minutes to church, then back. Then this morning 30 minutes to work.

No idle problems, no killing, no jerking... I'm afraid to jinx it but it seems to be better. The only things that I did that needed it was clean out the IAC (there was some black buildup in there) and the TB (some buildup there), pull all the electrical connections and make sure the contacts looked good and put some bulb grease in there, and replace the fuel filter.

I hope one of those was my problem. The problem was very intermittent at times... Felt like something dirty or not properly connected or on it's way out...

Thanks again!



Allright, so no more dying or low idle. Now the throttle seems to be sticking. Again intermittent. I only noticed it today on the way home from work. Rolling to a stop, clutch in, engine should be revving down from 3000, instead goes up like I have the gas down...

I'm sure it's just a sensor... Or could the throttle actually be sticking? What might cause that? I just cleaned the TB over the weekend.

Thanks again.
