I suppose these two problems are unrelated.
Anyway, after the last autocross meet, my car developed a funny idle. When i start the car cold, it idles super rough and low like it has some wicked cams, and then stalls out. After the car warms up, it idles fine, but a bit high at 1000 rpms, which i figure i can fix by just adjusting the idle.
I did some forum searching, and it seems the cure-all is to clean the ICV. Now please forgive my ignorance, but where is the ICV valve, and to clean it do i just kill it with some brake cleaner?
I already fixed two vacuum hose issues and no change in the idle problem.
Second question of curiosity is as i was taking the intake boot apart to find vacuum leaks, i discovered a whole LOT of grime buildup on the inside of the boot and in the throttle body. Its like a dirt and oil mix, not goopy or wet, just dryish and caked. What in the world would be causing this?
Thank you guys so much for your help.
