I have a old 1993 Mitsubishi Triton MJ which is having a bit of an issue at the moment with acceleration. With the initial acceleration such as moving away from traffic lights the engine will often sputter and struggle and almost stall.
From my basic knowledge and knowing the fuel lines and filter aren't blocked I have come to the conclusion that it is a vacuum leak or issue with the pcv pump.
Is there any way to diagnose which it is before replacing parts?
Having said that, it's probably worth going through and replacing all the vacuum hoses anyway on a vehicle of this age.
