exactly like i stated in the title, my gf's 97 jetta 2.0 has a strange problem that i haven't experienced since my mk2 days. When she is just cruising along in 3rd, 4th or 5th gear, everytime she is accelerating through 2100-2150 rpm the oil light will flash and beep. If she is just rolling through 2100(not pushing accelerator) or lets off the gas the light will stop, and once the rpm passes 2200 the light goes off. The car just had an oil change, and the oil level is spot on, so i know this is not the issue. anyone have any ideas?
