Can anyone give me some input. I just put a new 350 long block in my
1993 chevy K1500 PU. I had the intake manifold cleaned at a machine shop, New distrebutor, cap, rotor, wires, plugs, o2 sensor, fuel filter, thourghly cleaned TBI carburator, every thing tourqed to spec.Has plenty of power and no noticible hesatation when cruising at any speed. Fuel pump was changed about 1 1/2 years ago. Starts right up. BUT does not idle worth a #@!&* . Bad in park, worse in gear. very bad when first stated in morning. Has been timed and re timed, all vacuume hoses checked and rechecked, idle speed control valve checked and cleaned. Please help with where to go from here.
