Any ideas? |
Like I mentioned in my other post
I have a 94 escort with a 1.9L engine and I had a similar problem and did a lot of research on this to save a few bucks. The problem with my car was the idle air control valve. The idle control valve is used for controlling air flow when not adding gas, something to make the car burn less gas. After thousands of miles that valve can get sticky. Some can be cleaned, mine had to be replaced. It was around 50 bucks. Now it runs smoothly hardly can hear the engine. If that is replaced and still you have problems than make sure that the egr valve is cleaned.
Here is a picture of the idle air control valve
