    The coil itself could be bad also - look for signs of oil leakage from the coil - if there is leakage, the coil is bad. Had a 76 honda civic 1200 I drove for work that had that happen - went through a deep puddle and the coil got wet and the car quit until it dried out.

    Long shot on an old post but was it something visible on the ecm? I'm having the same issues but the ecm looks good

    The failed capacitors are usually quite obvious - they will swell up, forcing the top face to bulge out or the capacitors don't get a chance to swell and they leak. It will stain the PCB around the failed capacitor. Some guys notice a smell like 'fish' emanating from bad caps as well (probably hard to tell as most circuit boards smell a little funky...)

    if its cutting out than its most likely a bad caps. pull the ecm and post a pic. if the caps are leaking than it will smell like fish.

    Some of those soldered joints look like GARBAGE. I would give the board a clean and take a fine tip soldering iron to a bunch of the joints that are looking questionable. As long as you don't jam heaps of heat into it you're not going to make it any worse.

    so would you say this is not stock? or are you talking about the brown marks? should i just replace it with a refurb one? im no expert on this so if you could point them out id be very greatful.

    Unfortunately those are factory... I would play it by ear (or eye, in this case) and add a dab of solder where the joints are sketchy. Refurbs can be just as bad - sometimes worse. We have had a few members that have had dud ECM's that had refurb stickers on them (really crap solder jobs...) Clean the board with isopropyl alcohol and a small brush to gently scrub the crap off the joints and use liquid flux before touching up the joints. It would be ideal to use a de-soldering iron before doing the patch up but if this isn't something you'll be intending to do again in a hurry, it's not worth the investment. You can do this no problemo - just be thorough and use a small tipped iron for control. I'll add a video just for the soldering content -

    https://youtu.be/5Pxuf94fdRQ?t=326 (this guy is pretty good and the UHF radio that he's repairing is similar in construction and lay out to your ECM)
