i was getting on my gsr the other night and wen i came to a stop it started to idle funny and check engine came on. I got a code that said all my cylinders were misfiring, someone told me to change my cap, rotor, plugs, and wires.


any answers are much appreciated.

 

start with the plugs, how old are they?

then the wires, any obvious damage?

then the cap and rotor, how dirty are the contacts?

then the fuel filter, how old is it?

in general, a good service never hurts.

 

is your car a 97? anyhow, i had the very same issue, i changed cap, rotor, spark plugs n spark plug wires, checkd injectors , nothing helpd it, then i found out the there was a wire to the ecu that was loose, so i just pinned it back in and it went away. maybe u can check ur ecu..

 

turned out to be a bad wire, the inside metal piece was broken off, running perfect now


it's a 2000

 

which wire and where? I'm having the same problem.
