Thanks a lot for the info. I will try it and let you know how I made out. I really appreciate your input!

 

Hi
I am replying to this post and hopefully somebody can read and respond to my problem, because I am also pulling the same code as the original person who posted on this. I have a 96 millenia, and Its a P0302, cyl 2 misfire. I changed the plugs and wires, and also had a leaking valve cover gasket replaced, but still have rough idle and some loss of accelerating power. I had it looked at two days ago, mechanic suspects a bad fuel Injector or even worse, leakage of oil into the cylinder, since he showed me the new plug in cyl 2 as being worn out on the spark end. Not sure about that, but do you think it IS a bad fuel injector, or is it something else. Any advice would be extremely helpful.

 

hey i hope you guys can help me cylinder 3 on my 98 mazda millenia 2.5 is missfiring i took it to a shop i replace the spark plug wires i replace the spark plugs, the distrubutor cap and the rotor the intake manifold the, massflow air sensor and the top cover gaskets because they were leaking but it still giving me the same problem
