The light came on last night. The truck runa fine. It gave a lean code at the ford place. They did not know what was wrong. They told me that it could be the plugs not gap right. It has ran fine for two years. I did regap the plugs the other day. They where at .45 and I put then on .33. JLP told me they should be at .30 and the nitrous co. told me .35 so I split them.

They order a MAF sensor for the truck. They said try that frist. I think I will change the chip to see if that will stop it.
