Performance Issue
My 5.7 Bad Boy is sick and needs help...
It has only 85,000 on it. The problem I'm having is No power, can't get past 5 mph, stalls out, and feel like its running like a 4 cylinder engine. I smell fuel and very strong rich odor. I did nothing to the truck another than just drive it. I haven't put any kind of aftermarket parts. So I scan my truck and get all kinds of DTC. The codes I was getting at time was PO172, PO440, PO456 and PO300. I took out all 16 sparkplugs and replaced them. The plugs were black with the smell of fuel. I replaced a cracked hose going from NVLD to the EVAP canister. I then cleaned the TBI and put everything back together. I cleared the codes and started my truck. I felt that this would resolve this issues, but it still doing the same. The only code I'm getting PO172. I can't get out of my driveway. I NEED HELP BAD...
