Here is advice: * I had the same problem. By the sounds of it your EGR valve is gone. It's what lets the car know how much gas to put through n what not. * Change spark plugs; worked for me at 110000km * I have a 95 Sunfire, and a few years ago it did this. I did all the common fixes, but nothing worked. I had them check the computer for codes but none showed up. My car stalled at a dealer, and they pulled codes. It turned out that my fuel pump was shorting and they replaced that and it has worked great ever since.

How do you change the timing chain in a Pontiac sunfire 2.2 engine 2001 year?

This is a fairly major job, but if you feel that you're up to it, I'd suggest that you pick up a Chilton or Haynes manual. I was looking at my Haynes just this morning, trying to find out how often the timing chain needs to be changed. I couldn't find that specific info, but did see that there are very good directions/photos on how to do that job. FriPilot
