i have a 4/1991 m20b25.
the car was auto when i got it and it would idle rough before the swap. after the swap and crappy idle is more noticeable. it has a intermittent misfire and sluggish acceleration from 600-1000 rmp. cap/rotor are new. fully rebuilt engine. timing is dead on. this issue happed before and after the refurbish. is it a bad CPS/O2? i need to test the spark plug wires.
