misfire after LG header install????
Hello everyone, I finished up my LG install last night and took the car for a drive only to find that I have what I believe to be a misfire. While idling the car has a sychronized "arc" sound along with a "body rock". I checked for plug wire arcing yet was unsuccessful, checked all the connections on the coil packs, double checked the ground strap connection all with no luck. My O2's are run correctly and everyhting seems to be in check, but it idles rough, and when you get into WOT the car breaks up similiar to a rev limiter....
Any suggestions????
All help is greatly appreciated!

UPDATE....... I checked the plugs/wires and seem to have somehow cracked a plug...For all those doing a header install remove your plugs!
I learned a good lesson.
Thanks for all the help you guys!

I found the drivers side to go in easier than the passenger side.
The driver slid in like butter form the bottom, while I opted to remove th valve cover and go from the top on the passenger and got hung up on the ac line, the air tube line, and the wiring harness....not that it was that difficult, but the driver side was so smooth....
Good luck!
