89 Cavalier runs rough at startup
My 89 cavalier, 4 cyclinder, 2.0 runs rough (misses) when engine is first started up. After driving for about 5 minutes it clears up and runs smooth.
This morning I checked the spark plug wires (in the dark) while the motor was running & I could see no sparks but I did see a constant blue light. Does this mean the spark plug wires need to be replaced??
I replaced one of the coils previously and it worked ok up until now.
I took it to a friend mechanic and by the time I got there the symtoms were gone so there was nothing to fix. It's driving me nuts. Someone have any ideas. TIA.
