Hi, I've got a 2007 Peugeot Boxer. Occasionally, and usually in 3rd gear, the motor won't rev up and the van won't accelerate with the accelerator fully down. If I put the clutch in then the motor will rev up. If I drop in to 2nd then it seems to rev up ok then I can usually go back in to 3rd with no issues. Any ideas? Turbo?
