Hey all, my 87 has an irratic idle. TPS is ok, new O2 sensor. It has a chip for 42lb injectors and that looks like what it has. It is making the car run lean then the computer dumps more fuel in and may be causing fuel wash to happen.
I would like to know if it is the injectors. I have put very few miles on the car since I got it. The injectors show electrically they are in line. It barely would start here in IL when the temp dropped to 40 degrees. I guess if you hold the brake and rev it a bit and build boost it runs well.
It has a new fuel pump as well with the hot wire kit.
Motor looks to have been rebuilt and the car has alot of upgrades including Hooker Super Comp headers,high flow crossover, a 3" downpipe,test pipe w/dump,3" dual muffler exhaust,adjustable waste gate rod,ESP front mount intercooler torque strap,B&M linelock,2004R w/Trans Go shift kit and billet servo (shifts very well) 9.5" 3500 stall,SFI flexplate
Also what should a compression test show for the cylinder pressure. THis is all with in a few % of each other around 130psi.
Normal?
What about hot idle oil pressure?
I'd like to maybe upgrade the chip, injectors, and throttle body.
What size would you go with to have a low 12 high 11 second car and would it still be driveable. Idle ok ect.
Thanks,
Rob
