I have a check egine light on. I got it check and the computer said that number 6 cylinder was missfireing. I went out and bought a coil and a spark plug. Nothing happend. I have not done a tune up since last spring. I have only put about 1500hrs miles last year, I do not think it's the plugs. The only other thing I can think is trying to clean the fuel system or something. Also the air filter is fine. Any idea folks?

 

by nothing changed do you mean your engine light is still on? if so did you clear your ecu of fault codes?

 

How come cylinder number 6 always mis-fire? Happened to me too and it was a bad coilpad.... I change that and also the coil harness also! Fix the problem but why always number 6????

 

Did you check for oil in the spark plug tube? leaky seal

 

Did not chage the coil harnes. I did change the coil pad, the plug and it was dry.
I'll have to try the coil harness then. I did not set the ECU fault code, could that be it?

 

Diagnose the problem and stop just throwing parts at it.
