need some help getting my car running

[Michel Paiement]

I've been having a little misfire problem what I've been trying to figure out on my car for the past few days and has seemed to lead into it not really running just over night! sounds like its running on 2 cyl, does not really rev up. With the peddle matted it will sputter up to 2,000rpm then die after I'm off the throttle. Ive changed out the plugs, wires, coil pack, and power transistor and nothing seems to change it. I am getting spark on all cyl not a 100% on how good of a spark it is but there is spark there... I performed a compression test and I'm getting 150psi across the board. I cant think of anything else here and its really bothering me input is welcome or i'm willing to pay someone to help diag the problem.

find someone with an ecu to swap out with ya - easy test if you can get a known good one to try.

[John Hartman]

yes I agree.  Try another ECU.

Also borrow some 'noid lights and test each injector harness for pulse.

also if you can isolate the dead cylinders, you can swap components over from the good ones and see if it follows.
