Idling Issues/No Throttle Response/Stalling While Driving

[Xemplifi]

Alright so first off, I have a 1990 Z32 TT. No modifications have been done to the vehicle (yet) and I've already hit a problem. The vehicle is idling really rough and usually just bogs down and dies. My oil pressure I've noticed drops to about 20 or less psi when I let off the throttle and seems to only get up to about 55 psi when driving. Today while I was driving, the vehicle stalled at about 15-20mph. The vehicle was at operating temperature when this happened. And also, on some occasions the vehicle doesn't want to go even if I have my foot on the gas and then randomly regains power. If anyone can help me out it would be greatly appreciated. I have a video here of the idling issue if anyone care to watch it. https://youtu.be/rFf44UaJYGI

Standard oil pressure warm idle is only like 15psi, that and the gauges and senders are not exactly super accurate, I wouldn't worry about the oil pressure. the rough idle si likely a miss, you need to figure out which cylinder first then we can work out why, with the car idling unplug each COP one at a time, the one that has no effect on idle is the cylinder to investigate, swap cop and plugs with a known good cylinder and repeat test, if the problem moves the issue is on the cop or plug if not it's likely a ptu or injector issue.

The stalling issue, is the ar an auto or manual? did it stall when you pushed in the clutch coming to a stop? if so, iacv.

Make sure all the pins\connectors on the ecm are clean and shiny..I had the exact same problem and going through all the connectors with crc electronic cleaner a wire brush and then lubing with electrical grease completely fixed the problem even though there were no visible issues with the connectors.

For the female ends that are hard to get to get an emory board(nail file) and trim it to fit in there.
