My '92 ford f150 5.0 is struggling. Idles really low, low oil pressure, oil in the crank case breather filter and air filter smells like gas. She stalled on me today when i came to a stop with the a/c off, with the a/c on she idles at 700rpm

Do you have a check engine light?

Try cleaning out the idle air control valve and also the PCV valve-let me know-

When you're done with the PCV valve-check and test the TPS and MAF sensor-
