New here, and need help!
I have a 2002 Saturn SL2 that i am having trouble diagnosing codes P0401 and P0301 on.
So far i have cleaned the EGR ports, Removed the EGR Valve and tested that the Car was able to hit the rev limit, cleaned the MAP sensor, Tested a known good plug on cylinder 1 as well as plug wire, and Replaced the EGR valve with a brand new Delphi one. The car has a rough idle and sounds like crap. I am at wits end. Thanks-Nick
