haha i figured it'd be a code like that, i'm not sure when i'll actually scan to see it becuz its snowing like crazy here so im not driving the gtp. But another question is, do i need to tune my car now that i got headers....i know i should, and it helps alot(i will get around too it), but is it safe to run the 3.4 with my mods? (headers, 104 plugs, tstat, cai, dhp pcm). My guess is yes, but i know every car is different.
