Well first off i have 89 lxi with a20a1 block. First off i just replaced fast idle valve, newer plugs and wires, newer cap and rotor, and it gots a cold air intake.
When i try to start it up i have to give it about 1/4 throttle and it takes a good 10 seconds to start, then it will idle at about 750 and after a while of driving it will most of the time will go up to 1500 idle and it has done this warmed up and not warmed up. i adjusted the screw right at the top of the throttle body all the way down and it stopped my car from having idle surges. I would like to now why it wont idle at 750. And then my car runs like complete ass from idle to about 3000 rpm, sometimes it will miss and backfire and as soon as i hit 3000 it just takes off and and drives normal. and the timing is right. My last problem is there is a whisting sound coming out of the throttle body when i apply little throttle. Im stumped on all of these and have been trying to fix them for a month or so, any help is appreciated.
Thanks
