misfire?
hello all, i haven't posted in a bit but im back with a minor problem. car seems like its mis-firing at idle, what's weird is it's only when motor is warmed up and when a/c is off! lol i turn it on and it basically goes away, still slightly there, but alot better. i know i need to replace my egr valve autozone scan test said so lol but ya would that even be related to this? its not a horrible misfire but i feel the engine "jumping" or however you describe it, rpm's move a hundred or two with it as well. any ideas on where or what to start looking into doing? thank you much for any input it is appreciated. oh and ect sensor for comp is new as the ecm is too, plugs and wires are only two yrs old, fuel system is cleaned once or twice a year as well as the maf gets cleaned, so i doubt it's any of those things. thank you again for any input
