CEL light
CEL light
So a few weeks ago my CEL comes on and i brought it to autozone.. i believe the code was P0401 which was the EGR flow was insuffecient. This is nothing to worry about if its a freak thing, but over time it can hurt the engine (too much heat). I reset the ecu and a few days later it came on so i reset the ecu and cleaned out my intake. I came on again today and i'm stumped. My car is running incredibly well and the only thing that changed was i put in new spark plugs (gapped to the apporpriate gap). What should i do??
