Had bad misfire was on multiple cylinders. Replaced plugs and wires. Did it again. Replaced fuel pump and regulator. Idle was better. Then check engine light came on and misfired again badly showed a leak and misfire on cylinder 7.
Cleared codes. No more check engine light but still occasionally idles rough and occasionally misfires. Misfire can be at start up, at idle, or while driving. Misfire lasts several minutes.
Rough idle comes and goes. By rough idle, RPMs do not fluctuate, just runs rough.
have the same problem?
