I think I found my problem with the p0171 engine code I got. My truck is a 01' job1. So I have a different intake. The 2 vacuum hoses the come from the pcv had collapsed.
:banana:I had the same code PO171,PO174 looked at the PCV Elbow and found that it have a split in it on the top of the curve, so I reaplaced it and disconnected the battery for a while and code hasn't come back yet.
