Ok, after a new fuelpump and further diagnosing, there is nothing clear to pinpoint what is making my SHO stall and above all. . . slow. The shop I took it too said it's an electrical problem and they didn't have specialized equipment to go any further than their computer scanners.
As you can see in the sig, the car has many new parts. The exhaust is freeflowing, the intake is freeflowing, the fuelpressure is great, shifting and trans are good, handling is pretty sweet. But according to HunterVF it's as if the car is fighting to rev. We did new plugs, wires and well seals, IAB/IAC and cleaned out the intake with the 60K service. The waterpump had been done by the previous owner and apparently with a new timing belt as well. We didn't touch that however and couldn't see if the CPS was ok. However the shop said the CPS and cam sensor, MAF, TPS were all showing correct voltage readings. There are no codes in memory now, even though it'll still stall, when I make it stall by hitting the gas at idle or by accident. Before I had different codes related to the fuelpump, but they haven't returned since. So I think that puts to death the theory that they were popping up due to stalling. The compression test that I was able to do on four of the cylinders, turned out great, 230-240psi. I doubt the other two are bad, acceleration is smoothe, not jumpy(except for that 4K secondary "magic"
) Cylinder balance test showed nothing wrong with injectors. Can't run a key on engine on test, because it'll stall out when it starts to rev.
The car put down 125fwhp at Spring Zing, later that night we swapped out the old cats which were clogged, I noticed a nice difference, the car has an easier time past 5K now. And with the MAF I'm going to say I'm probably putting down about 140 to the wheels now, give or take. However at the strip, my best time so far was 17.7, granted it was hot, and it was my first time at the strip with a stickshift, but I was still disappointed with it being slower than my previous GL. And that's what makes me at myself, I should have stayed with the "SLO" and beefed that up with the amount of money spent on this SHO thus far. But I love the SHO, I love how it's loaded, and love how it can get up, I just would like it to get up to what I always thought an SHO would do.
Anyways, where else can I possibly go from here? After all that's been invested, I've exhausted options and I guess I feel disappointed at the results thus far.
