AHHHHHHHHhhhh!!
My car has no Power!
Here's the story:
I moved from Edmonton Canada to Dallas TX a month ago. On the way down I get detonation (Funniest sounding detonation as I thought it was an exhaust leak). So I take out my ADS chip, with no real change (except less power

). I get down to Dallas and my car is still running real crappy.
I take it to a shop and in order to get rid of the detontation they had to back off the timing to
0, (yes that's ZERO) degree's. The reason, I am told, is that the computer is used to Canadian climate and needs to adapt to Texas heat and humidity.
So now my car is slower than my wifes frikin' Chev cavalier!
The guy at the shop said that I could reset my computer completely. How is that done? Disconnect battery for 48 hours? When I reconnect am I going to have a problems (other than the sh*tty
0 timing??
I need some help, otherwise some dam ricer is going to try and race me and then claim he beat a V8 stang

.
I can't let that happen! Advice, please!
