Intermittant stalling and lurching

[cmac2012]

Might be worth your time just to get a different harness. If the same issue persist you can at least take the question of wiring out of the mix.

That was a thought I had. Another thought was to get a new harness along with an M52. Could still find such a harness at a boneyard with some life still left. Finding an E30 325i harness that you know is good might require going new, and I've seen prices of 4 to 5 hundred.

This car has 450k approx so perhaps not the best donor. OTOH, I do own it and even a lower mileage donor should probably have new stuff put in, suspension etc. I had never given the possibility of putting in a twin cam much thought but the M20 still runs pretty strong though it eats CATs and you can tell it's getting a bit weak in the pins.

It's a dilemma, putting in just a new harness I mean, I would like to get it running but I've already thrown about $200 in new parts at it to no avail. Not that much money but the thought of those brand new parts going to a boneyard is tough. Not sure how I'm going to test the harness to identify it as the cause. I'll look into that.

Any chance you figured this out? I've been chasing this same issue.
