I put a new fuel pressure regulator on it.. I have put 3 different IACs on it and it is still idiling shitty.. when U push in the clutch it will die.. and when sitting in the driveway it will idle fine for a while then it will take a spell where it floods like a bitch then smooths out and the check engine light will come on.. im clueless... ok for the other problem.. when I go around a right hand curve the dash lights will flicker... it wont do it sitting still tho.. U have to be driving it... I put the ignition switch out of my other car on it.. didnt help.. put a turn signal swithc on it.. no help.. put a differnt dash in it didnt help... im about to shoot the thing .... PLEASE HELP..

With the idling problem, scan for codes. You will have one or more stored because of the check engine light. If it's Code 41 (too lean), suspect a vacuum leak. I had a problem like yours, it would idle okay for about 10 seconds, rev really low and stumble then pick back up, and then I'd get a check engine light. I had knocked the PCV valve off of its hose by accident.

For the dash lights, try taking the steering column shroud off and wiggling the wire bundle around.

It's a good idea to put hose clamps on the pcv hose, especially the bottom one as they tend to get lose with age. Checking it with a vacuum gauge would also be a good idea.
