I just got my car back from my mechanic. The codes were bank 1 lean so he cleaned the egr valve and the mass air and it solved just about everything. no power loss anymore and the ruff idle is just about gone. There's still a ruff idle but no where near as bad as it was but it's still noticable and was wondering what else could be causing the ruff idle? It just had a complete tune-up(wires,plugs,pcv,etc,etc) any help would be appreciated.
