I hooked my code reader up last night, and those are the codes I got. After some research, I found the two biggest contenders here are intake gasket leak or fuel system problem. I plan on checking fuel pressure tonight, cleaning my MAF sensor (common to make P0101 show up), and have even been told intake bolts will work loose. From what I understand, my truck has the returnless fuel system (started in 04?), so if pressure is low, it will about have to be clogged filter or pump.
The reason I checked the codes is because I'm starting to get a lull in moderate acceleration, almost like driving a diesel that has bad turbo lag. When I'm accelerating, holding my foot in the same spot, it will accelerate for a bit, kind of plateau, and then surge forward like I mashed on it. It has had what felt like a miss at idle for awhile, but ran fine at other RPM range. Also, the new found dead spots seem to only happen when the truck is at WOT, although it warms up pretty quick so it's hard to get a lot of time to check. The truck has plugs and wires with about 20000 miles on them.
Do any of you have other things I should check as well? The bad part is I don't have a spare vehicle right now, so it can't be down for too long, and I don't have a ton of money to just throw parts at it. I also don't want to drive it too long with both banks running lean, because I don't want to ruin the motor. Thanks guys.
