Have a problem with my Navara whereby I get no appreciable boost below 2200 revs. I had to replace the turbo as the shaft broke on the input side and noticed while doing some diagnostics on turbo failure that the pressure feed from the intercooler to the MAP was disconnected.
Things I've tried to get boost at circa 1400 revs are, replaced boost control solenoid, replaced MAP sensor and checked for vaccum leeks. (I'm going to put a vaccum gauge on the pipe to the turbo actuator in the next day or so).
Using a diagnostic tool, I can get about 18psi boost and fuel pressure looks good as well.
I notice the the linkage on the actuator doesn't flutter on idle, this may be an indicator to someone here.
Also, (probably unrelated but in case this has been seen by others) my temp gauge jumps between cold and actual temperature until such time as engine heats up and holds well thereafter. I'm going to replace it this evening. Any pointers would be appreciated.
