Re: Code P0174 &P0171 65 miles after LS Swap installed.

Still can't get a scan tool until Tuesday. This morning I disconnected the battery to reset the light and removed and cleaned the MAF. Found a loose hose clamp at the throttle body/coupler. Once I put it back together no CEL.
But today when driving it came back on, when I was accelerating pretty hard getting on the interstate. Sprayed brake cleaner all around the intake manifold and no change in idle. Ordered a new MAF, and parts to move the air filter and MAF away from the throttlebody today, hopefully this does the trick.
