1999 Acura integra with under 150k
- At cold start, random misfire at idle on Cyl #4, #3
P0300, P0304, P0303
- Once warmed up misfire happens around 2500rpm, and could be on all 4 Cylinders
- Car thinks lean condition total FT over 10% (6+8 = 14%)
Changed PCV, Sparks, Wire, Rotor/Cap, Swapped Coil, Front O2 sensor, air/fuel filter are rel new, cleaned IACV, good compression, battery/alternator are good. Valves were adjusted 25k ago.
Where do I go from here?
