so i had these headers installed a couple of weeks ago, and now i've had nothing but trouble. 2 days later the c.e.l. came on. nissan was doing recall work on it anyway, so they cleared it. same thing 2 days later. spencer low racing assured me i wouldn't have these problems, but guess what, they're here! i had the codes read, 2 were popping up. the first is a catalyst deficiancy-not enough exhaust gasses moving through the cat. the second is the knock sensor receiving "high spark input" (?) i called slr about this 2 weeks ago, then again today. he said "he hasn't been able to get up with his tech about this, but he should be in tomorrow." if anyone knows what can be done, let me know. i'll update as soon as i know something.

wondering about the results of the catalyst deficancy problem
