Cylinder 3 misfiring: problem: PO303

by **thenewguy** » Thu Dec 10, 2009 4:18 pm

the 3rd cylinder is misfiring in the engine and im getting an engine check light. causing the whole car to shake. i've started off installing the spark plugs(front 3 are done already and need to do back three now.. :-?

) i've also put in fuel injector cleaner in my gas tank. Any other suggestions of what else it might be?

lol it seems like its one problem after another....ughh :drinking:

lol

Thanks

I had a bad wire cause the problem. Got a new set of NGK wires from advance auto for a good price.

so i checked out the wires at ngk.com..
if it comes to that would i only need 1? or 2 for all 6 plugs?

oh one more thing.. im having trouble in taking the back three plugs out. the space is so confined back there. :evil:

there a certain way to pull those back 3 out? or do u just have to muscle them out.

3 plug wires. If you can reach back there and pull them off...you should be able to get the plugs out

on my car the wires going from front bank have numbers on them "1". "3" and "5" and I assume thats where they go, but since you have them all messed up I'll go take a quick look for you
