desrtrat Posted February 12, 2009 Report Share Posted February 12, 2009 this didnt start until all the welding was done. It has to be electrical, when your exhaust was wielded up, did they disconnect your battery a lot of amps being used when welding, and a lot of components in our trucks are voltage/amperage sensitive, maybe your O2s just got fried good luck Quote Link to comment Share on other sites More sharing options...
