I'm going to. I'll get the code checked and start poking around. I haven't seen, heard, or smelled any leaks from the injectors so far.

So my oil pressure goes to 0 at idle after driving for long periods. No bad oil leaks or anything. The oil sensor is new. When I first start it and drive around everything is fine...it's only after long periods of driving...any ideas???

my comanche is doing this too. It's not as bad with rotella 15-40 and Lucas oil stabilizer, but I'm thinking it's my oil pump. Also, what oil filter are you running?
For you stitch next time you change the oil, throw a qt of trans fluid into engine oil and let it run for 10-15 mins ( I've heard driving is perfectly ok, but I don't do that)
BEFORE YOU'RE LIKE WTF IM NOT DOING THAT THAT SOUNDS CRAZY...I said the same thing!!! Transmission fluid has A LOT of cleaning agents/detergents in the fluid that helps clean up the inside of the engine, without damaging anything. If you were to buy an "engine flush" chemical, it's be way more expensive than a qt of trans fluid and BASICALLY the same thing.



check engine light. Going to go by Autozone and see what's up
