Any S14 knowledgeable people here?*

I’m helping out a guy who is experiencing trouble with his S14. Short walkthrough: Driving home from it’s winter hibernation, the car started to cough and jerking and has a very rough idle. Dies and doesn’t wanna start again. It apparentaly only starts with jump starters and has a rev limit of 3000rpm. The engine light is on and the car is running rich. ECU fault codes aren’t a option because he is supposedly missing the knobs and dials on the ECU to check for codes. I have submitted a video of how it acts up.

Taking off the air mass/flow sensor doesn’t do anything etc

*Posted in both DIY and S14 forum for maximum help.
