Ok here are the particulars..... 2007 3.5ho I added a custom dual exhaust which sounds great but wanted to get some better performance. I read all about this PCM reset where you pull fuse 11,14,17 and turn the key and all. So I take my laptop to the car and follow the directions step by step. When I crank her up to got spin some tires ( hopefully ) and wow the check engine light is on. So her I sit all dumbfounded. I think...... hmm disconnect battery and try again, no lets go see what the forum has on it.... NOTHING. Anybody know whats up or how to fix it without a trip down service lane? My wife is going to flip if she goes to work Monday and sees that engine light. OR is this going to go out after enough driving is done????? I know there was nothing wrong b4 I did this. Any help much appreciated. Please PM me.
