| 92 NA with 84k Tried search but this problem was not found Problem - Just recently this started, at a restart about 30 minutes after car was shut off from a complete warm up the engine sounds and feels like it is running on 5 cylinderes and after about 30 seconds it clears up and all is fine for the rest of the run until the next time it is shut off and restarted when warmed up. No problem yet at a complete cold start. Plugs were replaced at 60k with NGK correct #
No vacuum leaks, 20"hg at idle with steady needle
PCV's and hoses were changed back at 60K
Throttle bodies cleaned
Fuel filter changed at 69k
Air filters are clean
Recently put Seafoam in gas, no results yet My thoughts: injector going out
fuel pressure regulator out of spec
fuel damper problem
intermittent coil problem
carbon on a spark plug
EGR slightly open Any ideas on what to check is appreciated TIA
