When starting, the idle surges 700-1200 rpms for a bit then will normalize, also happens when coming to a stop at times (car in neutral). I consider this pretty normal since I completed the engine swap into the Fiero and didn't think much of it till today.
I drove around about 30 min and then parked for an hour or so before starting again. It fired up and then died twice in a row, then the third time I gave it some gas and then it stayed running and the idle fluctuated again before normalizing. I can hear the fuel pump priming and running each time as it sits right below the center armrest so I don't feel it's a fuel issue.
First thought is it could be either the cam or crank sensor starting to go out. It's a junkyard engine with about 80k miles on it, so it could be time to replace them anyway. The engine is mated to a manual trans in my Fiero and has ran great until this mishap today.
I'm wanting to drive the car to central IL this Saturday and want to address this before it comes back again.
