ok well the cars idle isnt that great. it bounces around when at a redlight or stop sign. sometimes even dies. thought it was beacause of the new alternator i put on the car. when i turn the car off and the turbo time is letting it cool down it idles perfect. i now think its because of the amp/sub i just put in the car. which would explain why it idles bad when the amp/sub are on and good when they are off.

how can i fix the idle problem with out having to take out the amp and sub.

 

maybe when you put the alt in you either cracked one of the 3 vac lines behind it or pulled one off. look behind the alt there are some vacume lines going to the UIM make sure those are all still on

 

i will check in the morning before work
