BlackMess Posted March 7, 2005 Report Share Posted March 7, 2005 My check engine light came on today so I had the code pulled at autozone. Came up as auxiliary emissions 1491. Motor is the 4.7 Person at autozone said gas cap. Replaced it but light is still on.. Any ideas about what it could be? Quote Link to comment Share on other sites More sharing options...
Crash1647545504 Posted March 7, 2005 Report Share Posted March 7, 2005 Did they clear the codes after they put the gas cap on? They have to clear the codes it wont just go out by itself. Quote Link to comment Share on other sites More sharing options...

grease monkey Posted March 14, 2005 Report Share Posted March 14, 2005 take to reputiable shop, and pay for diagnosis, auto zone scan is a good start, but the guys at auto zone are prone to throwing parts at the vehicle in hopes that it will fix it, you need to see an expieranced tech, that can diagnose the problem and repair it. other wise you're just wasting money on parts that probally don't need replaced.
