    Angry 2001 chevy tahoe oil pressure

    does anyone know what would cause the oil pressure to to up with accelleration and back down with decelleration. i get about 40 psi when idle and jumps to around 70 when im driving? i have about 123k miles on this suv. always change the oil at 3500 miles. i use 5w30 oil. also dont know how to reset the change oil alarm. ive tried the gas pedal 3 times but it doesnt work

    insane1 - It could be just the oil pressure sending unit or the gauge. Use a manual gauge to check it (its usually the sending unit). We have seen some oil filter cause this problem as well.
