Had my OBDI m52 e30 swap running great for a while now. Until this last week. A squirrel chewed through my engine temp sensor for the cluster. So... I ended up taking off the intake to fix that. I found a few other problems when I did.
In my hurry to get my car running (when I was first swapping it), I had some friends help me throw it together. When one of them put my intake manifold on, one of the gaskets fell out somehow and was laying sideways. Car ran surprisingly well that way haha. I deleted the "cyclone" from under the intake, leaving me with a few options to go from ICV to intake. I used the "turkey neck" hose and called it a day. Long story short, that didn't seal the greatest. I fixed that while I tightened up a leaky coolant hose, put in new intake gaskets, and a few other small things.
I started it up after putting everything back together, and it worked pretty great! Idled a bit lower, and more stable, seemed to have more power, and my econometer gauge finally worked (I suspect because I'm not sucking in extra air haha).
But... I was driving around town testing it out, and all was well until I got to a stop light. The idle kind of bounced from around 600-1000 twice and then stalled. Started right back up again and seemed fine. It didn't happen every stop light, but there were times I would push in the clutch and coast and the revs would fall and it ended up stalling out. Little odd.
I'm not sure yet if this only happens when it warms up, but..
could this be because I wired the coolant temp sensor for the cluster backwards? I doubt it because its for the cluster. anyways.
I don't think its another vacuum leak. could be, more tests tomorrow.
Could it be because I ran it so long with the huge amounts of air leaks and such that the ECU learned to make it run well with the huge amounts of air leaks and such, that I need to reset the ecu and let it learn it all again?
Any other ideas? Thanks for any help in advance.
