replaced coils and still really rough idle
ok i have a 2004 MT w/CAI and exotic speed exhaust
never had anything but 93 octane in it and mobile clean 5000 5-20.
hard driven every couple days
so i have a problem with a good start but hard as hell idle ( sounds like a old chevy 350 with a cam the size of a grape fruit )....i do a couple days of research and figure its the coils so i buy new airtex ones and put them in this morning.....start the car up and to no surprise **** stilll rough idle. i then proceed to look for vacume leaks and cant find anything but i do notice that the air pump is on so just out of curiousness i unplug it and the car about cuts of and then idles fine. i let it warm up after that and take it for a drive, i get to a stop light and the idle drops to about 500-800 rpm but jumps back up. i leave the light and i notice that the car does pull a little better and when i did a uturn u come back home it kicked out a lil better so i know my coils were goin bad........so i get back home after a good bit of "high reving" let the car cool down and start it again and it still rough idle with and without air pump connected ANY IDEAS.....MY BABYS GETTING A TURBO IN THE NEXT MONTH OR 2 AND I WANT HER UP AND RUNING GOOD BEFORE SURGERY LOL
