tracking down a misfire.

[lehrskee]

i have an 02 gt with 47k miles. ive changed the plugs, cleaned the maf and cleaned the iac and i still have a slight misfire. Its only at idle and you can hear it "pop" and feel it shake when it misses. any ideas?

Have you hooked up a code reader to see which cylinder is misfiring?

a coil might be going bad.

That's what I was thinking. Maybe see if you can get a new coil and swap each one out until it starts running good. Then you know which one it is.

COPs are pretty easy to swap in and out. Let us know.

ok that will be my next thing to try.

Could be a vacuum leak.
