Ok, for starters i just joined this forum and love all the knowledge here! please excuse my spelling and bare with me. LOL
For starters I have a 1990 Tracker 8v....yeah i know, one of the bad ones.... did not know this until after buying it! Now for the "issues"
The car upon crank up idles to around 3k RPM. Sometimes it will idle down to 2200 after warm, but not always. There is no high idle dash pot, it was removed prior to my purchase, and the vacuum line has been plugged. The is no EGR module, and the EGR valve has been blocked off, and i also capped vacuum lines. Found plenum gasket to be ripped, and replaced it. "thought that was the problem, but not so much" Tested the ECT and it tested correct "350 ohms when hot" but had a new one so I went ahead and replaced it anyway. Found old plugs gapped at .055", so bought new NGK and gapped to .028 per FSM. New rotor and distributor cap, plug wires, ignition coil ISC valve...ect. Cleaned IACV and seems to be working properly "smooth and springs back". I have not Changed the idle one bit!!! IMMA BOUT TO LOOSE MY MIND!!!! I have used at least 4 cans of carb cleaner and cannot get my idle to change one bit after the new plenum gasket. I can take the air cleaner off and cup my hand over the horn on the TB and get it to idle down, or even choke it down if I close it all the way off. I get NO vacuum the line of the vacuum advance line to the distributor. I tried unplugging the ECT sensor while engine running and had no change in RPM. What in the world could do this to me? By the way "i can
