You can fix the late model one to work. You dont need to replace it.

Okay, update: Dave's piece helped a bit but not by much. Still misses really badly at low rpms and hunts a bit when idling. Not much of a change between the mad being unplugged and being plugged in.
Fred, the fuel pump connector isn't very tight and may have an issue. I will replace that Monday. Going to grab a spare maf from an awesome friend of mine and swap the good maf tomorrow. Will report back results.

Hi Schillingster.
Again, m20 related, but I have dealt with a similar issue for over a month.
Start up, very low idle trying to correct itself.
Have to gas it or it will turn off.
Runs fine though at operating temp.
Sometimes shuts off when cruising if I let the idle drop when I press the clutch.
Happens on all start ups 80% of the time.
Just fixed this tonight and it turned out being the coolant temperature sensor.
Considering mine was bad, the ecu doesn't know the coolant/car is cold and wouldn't richen up the mixture to keep the car on.
AFR gauge at idle was 17-18 and struggling to stay idled untill warmed up.
Now, with the problem fixed, it starts cold and maintains 12-13 until warm and stoich with a healthy idle every time.
So yeah, my issue = coolant temp sensor (ecu)Comment
