No Oil pressure Stop Engine Safely,Yet Car was running fine.Starts and Runs Engine check light came on the text msg ,I Dont wont to Drive and ruin an engine What should i do.I had a computer issue @48000 miles the warranty on the computor was extended to 125000miles.When I got home I checked the oil cap it was wet with oil/I pulled the dip stick and checked it level was good but the oil seemed cold.Its only about three miles home the engine was warm.My car has 63000 miles

Do you mean the Check Engine Light? If so you need to get the engine codes read with a OBD code reader! This is the only way to be sure of the problem area!

milky oil means water/coolant is mixing into the oil, most likely cause based on the described symptoms is a blown head-gasket

This happens with a couple of my GM cars. I wouldn't worry about it much.

Check the oil pressure manually with a gauge. Make sure you have oil pressure. Perhaps you need a new oil pump, or new lifters. Get a professional opinion from a non interested party. Save money, get a diagnosis.

I would check the fuel pressure sounds like it could be low when there is a power load put on it.

run the fault codes
indicates dirty oil or problem in the oil pressure regulator /filter or servos

hello there
I looks like your oxygen sensor,Try to disconnect and then see what the car does?Let me know.You may need to adjust the fuel mixure,seem it is running a little rich that is why the car in idle goes up and down.

Check your fuel pressure. And your fuel pressure regulator.

Yes, the sensor is in small housing the goes in the hole where the distributor used to go. That also drives the oil pump so don't drive it you'll ruin the engine. It's located down under the throttle body, near transmission end of the engine.
