My friends 95 zetec has been having problems with a messed up idle, lurches low and back up alot. CEL comes on occasionally, but goes away before you can get the codes read. Apparently he's had some problems with the EGR in the past, so he's thinking about cleaning it, and I'm gonna help him.
So how do you clean the EGR, and how hard is it?
I don't know much about the EGR, and what I found searching didn't seem to answer my questions. I'd like to know as much as possible about this before doing it, and right now I know very little. Any help is appreciated, Thanks!!
