Will not idle
I purchased a 1990 GXL NA automatic to give to my daughter for her 16th birthday. Purchased with bad idle. Thought it would be simple. Lost $370 at dealer for diagnostics. Put in new Bypass Air Control Valve ($470). Have 6 volts AC at BAC connector w/10kohm resistor in place. BAC ohmed correctly. TPS's ohmed correct, checked TPS's with lights - OK. When I turn adjustment screw on ThrotBody for 1400 rpm starts seeking between 1000 and 1400. Stalls when put in drive. Runs the same with BAC plugged in or unplugged. What does screw under red cap on top of engine behind ThrotBody do? Car drives great speed. Tomorrow I'm supposed to tie a big bow to the car for the birthday part and its going to be a big dissapointment. Any help. Thanks!
