i was bored and i decided to change my spark plugs yesterday, so i went to crappy tire and instead of getting the oe replacement plugs for my gsr the
(double plat) i thought i would try the G-power plugs. so i put them in, then i reset the ecu, then when i started the car it started nice and quick, but when it idles it idles fkin rough... any ideas why? i made sure i gaped the plugs all the same to 0.052.

 

just double check your spark plug wire connections.

also gsr gaps are from 0.047-0.051. Maybe the 0.001 difference is making the car idle rough.

 

Hmm that is weird, that is the same plugs that i put in our teg and they are great. Car idles smooth. Maybe it is a bad wire?
