Ive went over the wiring, and turnd that damn crank angle sensor to every notch on the thing, and still will idle high low or like a v8

it starts every time but it wont rev and is detonating really bad at times so if anyone has any suggestions or advice i would be greatful thanks

Hello IF (IF) your timing is correct I would say look for boost &/or vaccume leaks. Go to FRsport.com they have a very good write up on how to set/check timing & CAS!!! PEACE

lift valve cover as per FSM to set timing, check for leaks, and your AICV could need cleaning too. wont rev- I believe that could be a MAF problem. people iwth faulty MAFs or wiring sometimes say they cant rev past 3000 RPM.

Yup I agree with redsuns that it sounds like a MAF problem. If you're using a KA24E or SR20 MAF, make sure the pins go to the correct place on the ECU - info available a lot of places, but sr-swap.com (Heavy Throttle) has the clearest page.

deff a maf problem, try picking up a z32 maf and follow bjorkluv's write up and see if that fixes your problem, and if not hey at least you've got a z32 maf for later

test the maf to see the voltage you're getting...
