Need some advice. My two engine codes are mass air flow circuit low volume and idle air control revolutions higher than expected.
I cleaned my mass airflow sensor, new air filter, found a broken air pump line on the front right side if engine and based on what I've read, installed a new PCV (pancake) valve. Ive checked all vacuum hoses and cant find any other leaks. I sprayed all lines with carb cleaner hoping to hear an engine rpm rise but nothing.
Any tips are appreciated and thanks.
