I replaced the power transistor (it comes with a new coil, bracket and wiring harness for $300. Ouch). It starts more reliably now, but the engine will stop unannounced after running for a while. It's an intermittent problem. After reading in other threads about how much the EA82 overheats, is there anything in the SPFI system that a high temp reading will cause a shutdown? All I can think of at this point is it's something in the throttle position circuit, or the injector itself, as it appears to be getting spark. I'm starting to run out of ideas.

I have an 87 wagon with the same engine, and the same identical problem. As best as I can tell, it's the power transistor, but not sure why it wouldn't fail outright rather than intermittently start/stop. In the process of trouble shooting this, I also encountered the throttle position sensor connector being severely corroded. I dressed it with some emery cloth and used a dielectric anti corrosion spray.

I have a similar situation with an '87 GL wagon, only it's an intermittent start/no start. As best as I can tell it's the power transistor, as there appears to be no other reason I'd get no spark. Why is it that it never shows up in the manual wiring diagrams or on any parts pages? Where can I find one?
