gee... you really need to find out why the SES is coming on.

Those issues sound like there is either a fuel delivery problem, or, an intermittent ignition failure.

I need to get my EASE system back from subman, if you need it, I can have him mail it off to you... do you have a laptop?

Do this first - make damned sure the battery connections and engine grounds are all good.

If you weren't getting codes, I would say a possible separated fuel filter.

If you could get down this a way we could take a look at it. I've got a few tools and a couple of FSMs. I just went to the garage and checked, I have the FSM from 89, 90, 91, 93 and of course 96. The 89 would be most applicable to your car. I'd start with checking fuel press. I've got a guage but you can pick one up prety cheap at advance auto. I would put the guage on and tape the dial to the windshield (if you get one with a long enough hose) and drie around for short distances with a couple of WOT blasts and pay close attention to FP.
After that I'd start on ignition checks.

Do you have any trouble on cold starts?

It sounds like you have some leaking injectors, this can intermittently flood the engine on warm starts and make it run like ass. Flooring it, cranking it, stop, then restarting normally would cure this condition.

Have you checked your fuel pressure after shutdown or while driving?

It sounds like you may have some other drivability issue aside from that. I don't like the check engine light coming on yet there's no codes. Does the battery clear it? Does the SES light come on with key on? Maybe an ECM problem.

There's gotta be a diagnostic page in the manual that tells you exactly what a SES light with no codes is caused by. It's gotta be the ECM, since it's never supposed to do that otherwise.

I'd focus on the verifiable problems before buying any fuel/ignition related parts.

Plus your time and money will be wasted trying to get a car running that potentially has a bad ECM.

They're just asking to see if the circuit is grounded somewhere and tripping the light. Doubtful since this is all underdash stuff. If the ECMis faulty and grounding it, it could be with the car on or off. So I would think you have to disconnect it from the computer before checking to see if the circuit is bad.

And obviously if it was an open circuit, it wouldn't light up at all. Also, does the 12V side of the SES light always have power? if yes, then a pinched off circuit would cause the light to stay on even when the key was off. So maybe your ecm is just grounding it only when it powers up.

Even if the ECM swap doesn't cure it you may be able to return the part.

Would it screw up the running of her car if I put her ECM in mine?

Have you gotten the TPS wet anytime in the past few weeks ?, washed the engine compartment? When mine went bad it cause the engine to load up sputter, stall, check engine light stayed on. Similar symptoms as mine, fine one minute and crappy the next. Water and dampness will kill it. Just a thought.

Changed the fuel filter lately? I had a similar problem with my 96. Had good fuel pressure but would stall or die on accelleration. If I'd wait for awhile it woud run, but not for long if I gassed it. I pulled the fuel pump and the FP filter was sucked up into the pump. I pulled the filter and it had a ton of $hit in it. It had pressure but no volume & no codes??

From what I have found, an ECM from an 86 or 87 is compatible with my 88. On the dark side I found a part number of 1227165. On ebay there is a guy selling one that is supposed to have come off an 85. However, the number is BUB 0122 7943. Would this be a correct part? I cannot find anything on a part number ending in 943.

There's no way the 85 ecm is interchangeable, it's a one year deal.
