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.
