Thank you in advance for reading/helping me with this. Obviously, I'm a noob to SQ. I am not new to turbo 4's, however. I'm addicted to Merkurs (which I hope you won't hold against me) and I am rapidly becoming addicted to this 86 Plymouth TSI beast, which is my newest toy. Issue: Car never shows symptoms until sudden ignition fail - generally at highway speeds. 10 failures at this point and never in city driving (not sure if related). Seems to happen after vehicle has been driven more than thirty minutes or so. Issue happens suddenly. Loss of tach and ignition. After pulling over and sometimes up to five minutes of looking at connections to ignitor (which I'm highly suspicious of) car will start and shows no symptoms. Might run 3 mintues... might run two days... no symptoms until sudden loss of tach and igntion again. Last night after two episodes within 3 mintues I tapped on the ignitor and eventually it started, but I can't be sure if it's related to my connection wiggling/tapping or just that the electronics cooled down and had less resistance. Does not appear to be ignition switch (inspected). Does not appear to be grounds on ignitior or ignitor connector (cleaned and reconnected). Coil replaced and connections cleaned. Please help if you have ideas. Thanks again.
