Oil in throttle body - Cutlass Oldsmobile Cars & Trucks

HI normaly the only areas i would look at other than possible head gasket,Check oil level is correct, is there is a blockage in the engine breathing side (possibly internal of rocker cover) sludged up. Or possible excessive crankcase pressure of course any one of these could lead onto the other if all the above check out ok then a cylinder leakage test should be carried out.(this is different to a compression test).Good Luck

It's normal, as long it's not pouring out.

Newer cars use what is referred to as "Drive by Wire. Instead of a throttle cable that goes to the throttle body, there is a sensor on the gas pedal and another on the throttle body. The signal from the pedal is sent to the ECM, analyzed, and transmitted to the throttle body to perform the desired operation. If something in that chain breaks down, the car is disabled as a safety feature, so that you wouldn't have, say, a wide open throttle issue to deal with. That is what the "starting disabled, service throttle" means. As far as the oil light and low oil pressure indications, if the key is on, and the engine is not running, these are normal indications since there is no oil pressure in the engine when it is not running.

This code refers to an internal throttle body fault. I have experienced numerous of these problems on this model. Most I have found, are due to oil contamination inside the throttle body caused by a plugged PCV system allowing oil to be pushed into the intake system. The repair I perform to correct this issue is throttle actuator replacement ( oil gets into the electronics/motor ) and PVC system cleaning. This is a relatively expensive repair to correct this problem. However, there are a variety of other reasons that may contribute to this code and the aforementioned may not apply to your vehicle

Yes clean the throttle body with throttle body spray cleaner and an old tooth brush with a terry cloth. Take air intake hose off of the throttle body assembly open the throttle body, spray cleaner all around on the inside, use an old tooth brush to scrub the grime and wipe clean with a terry cloth. Repeat until cloth shows clean.

The oil in the intake is likely coming from the pcv valve- blowby. This oil shouldn't cause any stalling problem although it can give some blue colored smoke from the exhaust. A car that runs is worth fixing.

The pcv valve vents the crankcase vapors into the intake to be burned. That vapor has oil in it and the oil will sometimes accumulate in the hose and throttle body. It's normal for all cars to have a bit of oil in there. Just needs to be cleaned out every so often.

Clean your Throttle body with throttle body cleaner or Deep Creep made by Seafoam. When the carbon and varnish build up in your throttle body get's hot, it gums up the IAC (Idle air control) valve which help moderate your engine's rpm to keep it from stalling.
If the IAC is stuck due to the gum of the carbon and varnish in your throttle body, you have stalling issues which you have described. Start with that and replace your air cleaner filter since your going to clean your throttle body.
Good luck and be safe, thank you for using fixya and post us back.

Stuff like: fresh spark-plugs, air-filter,new engine-oil, oil-filter, fuel-filter, plug-wires, rotor/cap, ( some adjustments may be necessary to the throttle-body and the throttle-body and choke cleaner may need to be sprayed inside the throttle-body).

A little oil is normal. Clean it with carb cleaner.
