bringing the old '91 318is back to life... most everything is working well, but i suspect i have just found another problem (i have an idea, but i'll not mention it to see if its the same thing you guys think)...
rev the motor to 3500, and give or take a few rpm's, it'll cut out instantly and drop RPM's and just as quickly come right back up to speed...
Independent of gears, or throttle position. i.e. if i hold it WOT from 1k RPM's and let it climb, it'll cut out as it passes 3500... same as if i back off and let it drop down to 3500, or hold it at 3500... the TPS is at a different location each time, so doubt its the TPS.
doubt it matters... has COP conversion and "stang" injectors (both seem to work well aside from this issue).
video of it sitting in neutral... you can't hear the motor cut out, but it follows the tach as the tach drops in and out at 3,500 RPM's.
NOTE: by the way, do we really have to sensor the word *****ded? (thats imbedded spelled correctly)... i mean really? Im trying to *imbed* the video of my tach, and i cant even spell it right, much less actually imbed it...
