I've got a day or two to return them. I tried installing them and then I think I messed up the firing order or something and ****ed a lot of stuff up. Is NGK better? Do Bosch plugs mess up the car? I think I fried my distributor cap. Are they really that bad? Should I return them or keep them? Are they stock or performance, and if NGK is better, how much better? Worth the hassle of returning bosch stuff, finding NG, buying, and then re-installing? Is it worth the hassle? What's the difference?
PS - I finally got the firing pattern right or so I think, but now when the car turns on . . it idles very very very ROUGH, like a ****en 50 year older roller coaster.
HELP!!!
