Having problems with your 1999 Chevrolet Tahoe ?
My 1999 Chevy Tahoe oil pressure drops when I accelerate from a stop. I am not accelerating hard. what is the problem?
Try replacing your pcv valve, which means positive,crankcase,ventilation, you will find it on the valve cover closest to front of the car. on the right side of engine[you did not specify which engine size you have] i hate to guess,so, suggest you repost your question with correct engine size,but it's not that hard to find,look for a vacum type hose that connects to one or other side of valve cover.it's a push in cylinder that gives your crankcase positive ventilation. i also suggest you change oil and filter,please purchase a good filter,such as fram,i'm not supposed to advertise for products so please ask your parts dealer for a productive oil filter.the only other two things it may possibly be is a bad oil sending unit which is located above the oil filter,may be unplugged,or bad unit. or may be oil pump going bad-[worst case solution] wish you the best and thank you for choosing fixya.com
