I have a 90 accord and it feels like its missing. I just replaced the spark plugs, the plug wires are fine. But its still really rough. How do I know if I need to replace my distributor? Could that be the problem or maybe fuel injectors? How do I know if I need new fuel injectors too? Thanks somuch dudes.

what kind of plugs did you put in it? How do the cap and rotor look? Did it just start all of the sudden one day or did it happen after changing something?

well it just started all of a sudden...i let my buddy drive my back to school and he said it was acting like it was missing...i put in bosch platinums and gapped them accordingly...i think the cap and rotor looks fine

first off remove those bosch and put in NGK, bosch have a bad habbit of frying coils in Honda's... Has anything changed? Timing, anything at all you changed on the car? If not I'd start with swapping in new NGK's and run some throttle body cleaner through the gas and seafoam through the engine (instructions for seafoam in the DIY section)

i think its the distributor...while it was running i took each plug wire out of the cylinder and the rpm only changed when i took the #1 and #3 plug wire out....wouldn't that mean that its only running on 2 cylinders and that is my problem?

were you running bosch plugs in it previously? It may not be the whole distributor itself....
