So i have an 01 lude. I just put a skunk 2 60mm tb on it and now it misfires. So i changed the plugs, wires, cap, and rotor, thinking that will solve the problem and to my disappointment it did not . Anyone have any suggestions?

 

Coil is just about the only thing left.

Weird that you put a new tb on and it misfires now.

Put the old one back on and see if it stops.

ALso make sure the injector is plugged in too, might have broken a wire while working on car

 

Ahh forgot about the coil. yea i put the old one back on and it still does it. it runs really rich now too. like i drove less that 20miles and dropped over 1/4 tank. could have messed up an injector wire but meh. ill go tinker with it and let you know. thanks man

 

still runs like crap

 

Have you replaced the coil. Its very hard to test a coil.

 

When the car is idling, pull a wire off of a cylinder, one at a time, and take note if the idle changes on each one.

If the idle drops, then that cylinder is fine, if it stays constant, then that cylinder has a problem.

The pull the plug, place it in the wire and rest the metal part of the plug on the valve cover. Turn the engine over and see if it sparks.

If it sparks, then the injector is bad, if it doesn't, then its an ignition problem.
