Rough idle, no codes?
After a series of codes and after replacing O2 sensors, spark plugs, and MAF sensor, I ended up clear of codes but still have rough and shaky idling. Does a vacuum leak bring up a code? I'm happy to see no engine light on my dash, but the rough idle worries me. Please advise. Thank you!!!
