Could be plug, plug wire, or coil. Check them first

yea guys thanks! well first of all i pulled the injector wire and that made the car run more harsh when i revved it and i also pulled the spark plug wire and saw some spark from the coil arcing on the stud, so what options are left??? i changed the plugs and wire lik 200 miles ago!!

Check to see if the plug fouled out. You might have bought a too cold plug. You also might be leaking oil.

Leaking oil??? the NGK TR55IX plugs i know are hot plugs! thats the reason why we feel a performance differance with these plugs! factory are cold if im not mistaken! but thanks for the help!

Yes, leaking oil. As in oil on the plug. Which causes a foul plug and misfire. I didn't necessarily know that you bought the TR55s. Sorry for the misjudgment.
