Re: runs rich, gas in oil

Check fuel pressure real close.
Check for proper pressure and or fast leak down.
Any engine miss fires or cylinders missing.
How are plugs and wires?
Other things can be TPS or map coolant and air tempt sensors to computer and MAF sensor if it has one.
Needs put on a engine capable scanner and read out all sensor data.

And also check for restricted exhaust system.
What is engine vacuum at idle and at 2K rpm?
