loss of power ZD30
ok this is the story. have a heavy loaded off road c/van, towing 99% of the time. have full nads done and all has been really good until now. before power problem at 100clicks boost sits at 11 psi and pyro sits at 440 degrees C in top gear. the last couple of days driving power has dropped off a tad. boost still reads 11 psi, and pyro has climbed to 520 degrees. all hoses vacuum lines appear fine. intercooler is good, so what the @#$& is going on. i'm at the stage to torch the thing! and god forbid buy a v8 landcruiser, can anyone help please.

Cooling system isnt blocked, good coolant?

Sticky injectors?

I'd Spray the MAF sensor to eliminate that from the equation,
You blowing extra black smoke that you can see.
Do one fix at a time so you'll know what the problem was

Just make sure its dry before putting it back, clean over some paper towel you'll see if dirty or not

will do, you might be right 3D, as the highway run today, vehicle went alright to start with, lost power and pyro went up, seemed to come good for a while then same again.
Have pulled out MAF sensor and was a light mist of oil on outside plastic, so here's hoping you were right, let you know after highway run tomorrow.

Try towing in 4th gear being in overdrive puts to much strain on the
little 3l try driving at 90ks instead of 100/110 and as above for the rest
could be due for a oil change

After cleaning MAF you should disconnect the Battery for 30 mins to reset the ECU

have got heavy duty valve body and lock up switch in auto, so no problems staying in top. but in saying that I do watch egt gauge and change down when temps rise. I think doggy you were right with maf as I did clean it and disconnected battery .todays towing run temps are around back to normal. bit hard to say being for a 20 knot head wind. at least I'm not getting egt's over 500 plus, more like 460 with head wind.
