1985 Pontiac Fiero Repair Question
Asked on August 5, 2012
V6 idles rough at first & backfires until warm
When first started it idles a little rough but not bad.Stays running. It will backfire 3 or 4 times when getting on it for the first couple miles. After that idles & runs fine. Lacks a little power when getting on it at the end of each shift.Replaced plugs, wires, cap,PCV & rotor @ 89,000. Problem just started a month ago. Any ideas?

could be running lean, the coolant sensor could be bad, could be injectors. a shop with a scan tool can monitor the sensors to see which one is out of parameters.
