Looking at the 94 I have, how do I read the date stamp again? What numbers do you have on the black side?

I've heard some things that don't sound substantiated by the club. But that doesn't mean it'* not possible. Sounds like at this point you've tried nearly everything.

is it possible you swapped a bulb out...specially in the tail lights that isn't the right bulb?
I've heard changing certain bulbs with the incorrect ones can wreak havoc.

Step Dad did it in a chevy truck and previous owner harped on it for 1/2 hour to really impress using the right bulbs on me. He had the issue as well with this car.

Timing Set

Oil Pan Gasket Set
Timing Damper
Antifreeze
Two Coils (Used)
Both coolant sensors
Spark plugs and wires
Repaired UIM
New Injector O-Rings
New Fuel Filter
Cleaned ICM Ground
Cleaned battery connections
Used MAF
I think I remember you saying the original TB made no diffrence either...

I'm not really sure what to tell you at this point except that you are running out of options in a hurry.... I was going to ask about the exahust but I see the High Flow cat and Res in your sig...

I'm doubtful that you even have a bad injector to begin with... Seems like some other issue... Your fuel pressure is good, so that tells us the new fuel pump and your Fuel Pressure Regulator are in working order... And from what you can tell the TPS is also in good working order... I think you swapped out to the Magnavox ignition module and still had simmilar problems, so the ICM should not be the culprit either...

Is there anyone that has a 92-93 with the Same PCM as you car that you can test with? Have you tried that?

Does the car backfire through the intake? Miss cough or stumble while trying to accelerate? Does it start up right away every time? Idle good?

And your timming numbers are pretty close to mine, Both cars... Mine idle between 13* and 19*.... I have seen as much as 39* advance.... Not sure whats going on there either...

Did you have any knock counts or Knock sensor issues? If you need a Knock sensor I may have one for you...

Short of the PCM being flawed I out of ideas...

It'* still running great. Here' some recent logs;

http://www.damemorder.com/scan/

The only thing I'm wondering is how to fix the rest of it. Light cruise can't happen at 2300-2500 rpm, it bucks too badly. It feels like the motor is overheating off the line, then gets and grabs like a ricer in the high rpms. What going on? It feels like a high torque misfire.
