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

I'd check all your air hose clamps, then check the timing should be 16°beforr top dead, and make sure the idle air is adjusted right, then test the coils make sure they are firing right. Then replace fuel filter an pcvs, the little things can cause big problems

Timing is adjusted by how the crank angle sensor is turned, right?

Ok, so I tried removing that yesterday because I was gonna do some test on it with my multimeter. But I just have to remove the 3 bolts and unclip the wires to the sensor right? Cause It wasn't budging haha
