Idle issue...or something... So in the past few days, I got my car running. I put on some rebuilt heads, stock intake, stock cam, but roller rockers, headers, and all the other bolt ons. I had a tune done by Trifecta, and when I fired the car up, it idled at 1500 rpms. I had it running for maybe a half hour, bleeding the coolant system, check the fan operation, and things of that nature, and the idle never budged. The next day was the same thing, idle never budged. Today while I was at work, my father turned the idle set screw down and it went to 1200 rpms.
I went out to check the TPS voltage, which was right at .65, I started pulling and capping vac lines, messing with the intake, the MAF, and anything that could cause a vac leak, and nothing made any changes. I go to take a ****, since I'm by the woods, I went to walk to my favorite tree, and just as I unzipped, the idle dropped to about 850. It now idles rock solid at 850 rpms. I didn't touch anything at that point, change anything, I can't figure it out.
Could this be the computer possibly "learning"?
