When my car is in idle it kinda wants to die. It idles around 500, and the lights kinda dim and the engine rolls a little. The dealership says it's the aftermarket parts and wants me to let him replace everything-fat chance. But the dealership and two "electrical specialty" shops are dumb-founded. Even my mechanic friends are getting pissed at my car. NOBODY can figure it out. I installed an air intake, header, exhaust, and brand new wires, plugs, o2 sensor, fuel filter, fuel pump, battery, alternator, and checked my fuses. Anyone have any ideas? I'll send $20 to the first person who gives me the info I need to fix the problem!
