car still not running well

[fabcal]

hey guys, I'm still having problems with my car. I thought it was the spark plugs I had to change but even after I did change them, car's still running on 5 cylinders. I've been told that sometimes water gets into the spark plug hole from condensation that sometimes happen under the plastic cover. To me, it's still the bad fuel in the gas tank that's giving me problems. Can anyone please tell me what I should do

I dont think its the fuel alone, as why run on 5 and not all 6 cylinders even if roughly?? I would say its either a bad plug or coil or plug lead.

i agree it could be a coil

it also might be a plug wire.. my car wasnt running to well.. changed plug wires and ran like a champ.. partsgeek.com is the cheapest i could find them for..

Hello
I am having the same problem with the miss. How do you find the bad coil pack with out a machine to hook up? Shop mechanic said I should change all the coil packs. That sounds like a parts replacer. ANY THOUGHTS

Thanks
