The engine wire harness is very expensive, and they will charge you an arm and a leg for labor also. I was charged 8 hours diaognostic time, since it took them 2 days to figure out my problem, which they said was a engine wireharness falling apart. They ripped it out, showed me, and I was like, fine, its goning to cost me a fortune, but do it. The problem was never solved. I guess the brittle looking engine wire harness was still fine.

I use to have a sound system in my car, which I only kept in it for 4-5 months. Mechanic said, it might be sucking too much power, and causing the occasional problem. I took it out, and it never made a difference, and changed the battery.....i had a rockford fosgate amp (225.2), 2 - 12'' Rockford fosgate subs, 1 - 12'' phoenix gold sub, and two 10'' Pioneer subs, all of them in there at once, my whole trunk was occupied. Took it out, everythings sitting in the garage. But car's still working like crap.
