aiight sounds good, why im thinking is if the sensor is shot it just not giving the pcm an accurate reading for the oil pressure

I just called, and they are pretty busy, I'm taking it in tomorrow.

I really wish I had looked at my gauges at the time it happens, then I could give more accurate info.

I'm pretty sure it's not the oil pressure sending unit for me because I had it replaced when I bought the car, it could very well be it for you, though. But if I had it replaced when I bought it, maybe it's just a part that goes out often and I'll have to replace it again? We'll see I guess...

Got the car back, here's what they said:

Code 77 on computer = EGR solenoid problem. Check circuit-possible carbon in valve. Idle Air Control position 85 at idle. Computer at adoptive limits and cannot control idle. Position set to 35, and fixed, throttle body cleaned.

Hope that helps.

Yep, Yep and Yep. Although I think they just cleaned the TB as a precaution. I cleaned the TB with seafoam about 8K miles ago, so I was surprised they did that. But it might have gotten dirty because of the other 2 probs. So now that I think of it, do all 3.

Good luck man.
