Idle trouble.
Hi, I have a 1991 Z28 Camaro that has a serious idle problem. My knowledge of cars only spans what I have had to deal with. The fuel pump had been changed, the diaphragm of the fuel pressure regulator has been changed(which was causing it to die at stop lights.), and I changed the fuel filter.
Howeve, the idle starts to flutter after about 3-5 min of running and I’m not sure what to try next. Thankful for any help!

Re: Idle trouble.
So it sounds like the problems begin when the car warms up and it goes into closed loop?
When you get a chance, unplug the O2 sensor connector the next time it's acting up and see if the problem goes away (ignore the check engine light that comes on).
