My 2000 Cavalier (2.2 standard engine with automatic trans) is all of a
sudden missing badly. It started about a week ago. I replaced the plugs
(they had about 25,000 miles on them and weren't all that bad) and it
cleared up a little. Now the miss is really bad and the engine is surging at
idle. The "Trac Off" light came on at the same time the miss started. It
goes away from time to time (during the last 10 mile drive) and when it
clears up the "Trac Off" light goes off.
What do I look at first?
By the way, where do I find the EGR valve on that engine. I priced it at the
parts shop and they quoted me $297.00 because they said it is "electronic"
Thanks for any help you can give.
