My 98 has a bad misfire in cyl#7 changed the coil, plugs, wires that did'nt fix it, and all the grounds look fine! The car also backfires! What the hell is wrong?

Default misfire

Take a compression check on that cyl. you may have a broken
valve spring, or bent pushrod.

I would take another look at the shop I working on my vette. I would think that would be the next logical step, and something they would have recommended.

Good luck and let us know what they find.

yah thats not good when a shop starts replacing thing without knowing why!
I would hope that they plugged it in to a scaner and tested the ignition first, and a leak down wouldn't be a bad idea either.
good luck

Swap the injectors # 5 to say #2 and see if the problem moves. If yes... you'll know what to do

Default Dont wait

Go to a local parts store (Autozone, Pep-Boys, Napa) but a compression tester and do it your self. Its very easy.......why wait till monday when you can check that..........I see a bad ring on the piston.....Blow By
