Ok guys, I am at the end of my rope and need some advise from someone more experienced with these cars. First, my current motor related mods are as follows: BBK Shorty Headers with high flow cats and true duals K&N filter High CFM Fan with independent Relay Now on to my issues. In the morning when I first start the car, it will not idle. It will die unless I rev it until it starts to warm up, and then idle's like its got a massive cam. Once driving, the idle will hang as high as 2k until i come to a complete stop. It will also backfire and miss under load. When the car is warm the in the afternoon the idle is better but still rough, backfire is less often but still there. I replaced the Idle air control valve last night thinking this was the issue, but no dice. My Mass air sensor is less than a year old, and I did find and fix a vacuum leak several weeks ago. I should also note that I have had an issue with my headers burning plug wires and causing a miss under load but have inspected all of my wires and they appear to be fine. Any help would be greatly appreciated, I love this car and would love to be able to drive it to its potential.
