I have high idle , around 1100 or little more rpm.
on datamaster desired idle is 650. recently I changed plenum gaskets, injectors, coils, spark plugs and wires because there was a problem with ingnition, miss etc. now the only problem left is high idle.
(oh maybe not the only

but most annoying)
I`ve read that tps v should be from 0.54 to 6v
mine at idle are around 0.24v
other thing is how to check iac?
datamaster shows that iac is 0 on idle , whem I rev a little it goes to 30 and them falls to 0, with it rpm falls but now as low as I wanted it to be.
is the a way to check iac? or to calibrate it?
