I am failing my emissions testing because my idle speed is too high, it has to be between 400 and 1100 rpm and I can't get this thing to idle below 1300 rpm.
84 4x4
2.8L
5-speed TK
A/C -- I think it may be aftermarket, not sure
Ignition timing verified @ 10°BTC with engine at operating temp
Verified all vacuum connections, don't seem to be any leaks
The manual says that the adjustment for curb idle is different depending on whether or not it has A/C.....I can't find the "knob" that the manual shows for a engine with A/C and the screw that it says to adjust for an engine without A/C has no effect on curb idle speed when I adjust it either way.
I have backed off the only screw that seems to effect idle speed until it no longer touches the linkage and it still idles high.....( This is called the "throttle sop adjustment screw" in the manual)
Any help would be greatly appreciated....I need to pass this last year of emissions
