Very high idle. PLEASE HELP!!!
#2
welcome.
and we can find it


Ok, for starters i just joined this forum and love all the knowledge here! please excuse my spelling and bare with me. LOL
take your time, and we can knock off the ducks.

For starters I have a 1990 Tracker 8v....yeah i know, one of the bad ones....
Their ok, just iSC's go nuts.

did not know this until after buying it! Now for the "issues"

The car upon crank up idles to around 3k RPM. , tad high, 1500 to 2500 (summer . /winter)
Sometimes it will idle down to 2200 after warm, but not always. (that is a huge air leak)
There is no high idle dash pot, it was removed prior to my purchase, and the vacuum line has been plugged.
Ok that means the owner (PO) did that to hide the bad idle issues.
Once we fix that leak, the missing DP will make engine flood starting ,but there is right foot action to avoid that.

The is no EGR module, and the EGR valve has been blocked off, and i also capped vacuum lines. (it will run ok , with out)
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" GOOD !

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. very good.

New rotor and distributor cap, plug wires, ignition coil, ISC valve...ect. You have a new ISC? really ?

Cleaned IACV and seems to be working properly "smooth and springs back". this is in the base of the TB, you fiddled that?

I have not Changed the idle one bit!!!
IMMA BOUT TO LOOSE MY MIND!!! do not worry, all leaks can be found. we canb find them from easy to find to harder. order.

I have used at least 4 cans of carb cleaner and cannot get my idle to change one bit after the new plenum gasket.
have you turned the TV throttle valve , screw CCW to close up the TV?

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. (smart move)

I get NO vacuum the line of the vacuum advance line to the distributor. (the port is plugged but that nipple i ported vacuum.)


I tried unplugging the ECT sensor while engine running and had no change in RPM. (wow that is messed up)

What in the world could do this to me?
By the way "i can
