Re: P1315 code after TSB repairs for P0171 & P0174
Is the van shaking?
The DTC points to a misfire problem, the raw fuel smell also does.
The first thing would be to inspect the plugs and wires, maybe during the repairs you damaged one or was already damaged; MORE IMPORTANT than plugs and wires is the coil pack. Remove it and inspect the back of it; it is known to crack at the back and cause arching to ground resulting in random misfires.
