I have a 92 Camaro with a 305 and 40,000 miles. When the car warms up it idles very rough and sounds like a motor boat. Sometimes it will stall, In most cases it starts right back up. I changed the plugs and the egr valve and there is no difference. Does anyone have any idea?

Thanks

 

Well you probably have a closed loop problem. Your 02 sensor may be bad, but there are many other things that can make your 02 read incorrectly. We will need more information.

 

Could be a number of things. How old is your fuel filter? How long since last tune up or new air filter?? Have you check for any vaccum leaks??
