so i got a 03 rsx type s and i recently had my knock sensor and o2 sensor fixed then the check engine light went off then it came on again for all cylinders misfiring and random misfire i changed the plugs and coil and still nothing the car drives fine no misfire when driving it just has rough idle idk what it can be any help would be apprecited thanks

 

could be a map sensor going bad.

 

Check the plugs. Swap around components. Sounds like a bad injector to me.

 

I have/got a misfire, replaced plugs, coils, injectors, map... still there, in my thread they mentioned that poss the timing is off, could have had low oil pressure and jumped a tooth or something.

I haven't been able to get the timing checked, but that is another option.

 

could it be a bad pcm i baught the car stock and the kid before had work done to it a flash on the pcm exhaust and header could the computer just be putting out the codes

 

I got those codes on my 04 turned out to be a burnt valve.
