Updates:
1- i wiggled the injector wires while reving the engine and it was fine, nothing abnormal happened.
2- cleaned my icv with carb cleaner and problem persisted.
3- unplugged the icv and the idle went up to arround 1200 rpms. Reving the engine and let go didnt kill the engine.
4- im waiting on a known working icv to arrive so i can continue diagnosing.

My bad for interrumpt, but what sensors are the icv and cps?

Icv - idle control valve. Let air move past the throttle body to maintain idle.

Cps - crankshaft position sensor. Tells the fuel pump to fire other then just knowing where the crank is I believe.

Op - I got tired of tracking down the same dumb problems with my m20 so I just went for the m50 swap lol.

Sounds like you are tracking down the culprit. Are you getting a check engine light at all? If not, it probably isn't a vacume leak. Also, what was the last thing you had worked on, or worked on yourself before this happened?

Absolutely nothing in the engine or electrical stuff. It happened all of a sudden. The engine was running very good since 2 years. Spark plugs were changed i beleive less than a year ago. I put about 10k miles on the engine since day 1 i have the car aka 2 years ago.

First the check engine light was not on at all, but now i have it shining in the cluster.

Hey thanks a lot for the info...As you, im getting tired of the m20, mine do all sort of things from time to time, right now it stall until pass 2500, and I can feel some weird vibration from the driveshaft, I guess is some bushing or something, everytime something broke...I love e30 anyways!
