so i have a 2006 ss/sc g85. aftermarket intake/exhaust, no cat, just recently replaced the stock clutch with the gmp stage 2, after doing so and driving around a bit i noticed a little bit of engine shutter. she idles rough around 600-1000 rpm depending on cold or hot, and i hear a slight ticking in the valve train by the timing chain. A long time ago I read on here about replacing the stock chain tensoner with the one in the LNF, but I can find the thread, and also dont know if that is the problem or if I F***ed up the valve train. anybody know of any place in San Diego that does trouble code readings for a fair price (free if possible lol) and if anybody else has had this issue any help/ advice is greatly appreciated thanks!
