    Yep, the one we were fooling around with. I haven't driven it much with all the rain making the surface very compromising. :oops:

    I thought it almost sounded like a low battery, but resistance could be it. Definitely need to do more inspection before cranking again...

    Out of curiosity, what was the reason for pulling the head? Most of what it looks like you've done could have been done with just the valve cover off. What issues were you trying to resolve? Was the car running? Were there any compression...

    I filled up the rarely used AEM Water/Methanol tank on the car. I am having a bit of knock up top, even on E. Boost Juice at 49% Methanol was my goto for now. I'll back the timing down after this "test". I haven't used it in years. ✌️You must...

    I've tried 2 other MAFs, one spare one I had and one from a good known working car. Using the US spec ECU and watching the live data I don't see any erratic MAF related signals. TPS also outputs linear voltage.If I hold the pedal until it...

    Hiw about this. Get the car somewhere dark and watch for acing issues. Yiu could have a crack on a coil tower and didnt spot it. Wires are almost certainly ruled out. I had a similar problem once and it was arcing at the spark plug boots but...

    Got to be careful of printed ones as unless it is an industrial printer, most will leave lines in them and create cracks. The best way is to use a proper industrial printing machine or, as we have said, if NO ONE comes out with a quality one by...

    have you tried swapping the MAF? The throttle being unresponsive and sometimes killing it seems like it could be a bad MAF signal. Along those lines, have you checked the signal from the TPS? Is the voltage a linear increase or does it have...

    I have swapped coils and measured the resistance of primary and secondary coils, all were within spec. By grounded properly you mean bolted to the intake manifold? If so yes. To me it sounds more like a "soft" injection cut rather than a "hard"...

    This indicates that the ECU was unable to lower the idle speed to it's programmed setting and has attempted to close the ISC 100%. You mentioned a bad ISC blowing the drivers in the MD305162 ECU. Have you measured the coil resistances of the...

    How are your coils? have you swapped those out? Are they grounded properly?I'm hyper focused on ignition because I had this very same issue and it was plugs/wires for me. Free revving it would break up close to redline. Then under load...

    Afaik, pinouts are identical and the car behaves exactly the same with both ECUs. My best guess is that outside the US OBD2 wasn't mandatory from 1996.Installed brand new BPR6ES plugs and gapped to 0.028". Wires are also brand new.The high...

    how new are your plugs and wires? how are the plugs gapped? Have you measured them?High rpm break up sure sounds like it's your plugs / ignition. Just because they were taken from a running car doesn't mean they'll work in yours. You...
