even when my car is warmed up, the idle sits at 1.5k. i've alreadly tightening the idle screw all the way. i've come up with a checklist. do u guys suggest anymore?

1.hose/vacuum lines: make sure they go the right spot.
2.hose/vacuum lines: make sure there are no leaks
3.eacv: clean out
4.radiator lines: i heard if there is air here, this might be a problem. but how do u drain this out.

 

ok the only thign i can help u with is bleeding the radiator lines. if u follow the large hose from the radiator, left center there is an aluminum nut/ u loosen the nut wait until coolant starts coming out, then tighten it. make sure ur car is cold
