When started car has loping idle sounding like its miss firing. Idle rpm ranges from 500-2500. While it is like this its making sound like sucking air really hard into engine.
When driving at highway speed when foot is on petal idle stays smooth and steady, but when i take foot off to slow down for exits, will drop about 300-500 rpm and catch itself and you can feel it stagger to a stop.
My next issue is that the obd2 port is not working when plugged into any scanner. So not able to read for any codes but the light is on.
Recently replaced idle air control valve since old one was carbon clogged.
Any pointers would be greatly helpful.
