So if you got limp mode without towing something then yes there is something else going on.

My point about replacing stuff remains valid and thanks for not taking it critically as was not intended - on this forum you will see dealers in particular just replacing things until they have fixed the issue only to have the problem return and ultimately solved with input form AULRO members.

On this last incident - have you had time to get the codes read?

Also the cost of a new MAP sensor is not a lot so as Graeme has suggested it might be worth replacing.

Also and I am going into an area I know nothing about - you have a suspicion about the turbo but in themselves they are pretty reliable however the actuator sticks - thinking out aloud is the actuator sticking and not allowing the vanes to go to the right position so causing the problem.

Maybe someone who knows could tell up if this is feasible and if the actuator can be serviced in place.

Irrespective I would replace the MAP sensor.

Good luck

PS - no checking of the turbo as yet.

My thoughts exactly about the actuator. I reckon it's a possibility she's either sticking or worn out. My other rig has a 600hp Cummins Signature in it but it's just before they switched to variable vain turbo's. I've heard that they're having turbos die after 200,000klms where the traditional turbos should last a million k's. id like to check the intercooler for leaks too before I go through a turbo swap.

Cheers mate

The actuators are known to fail and linkages become stiff but usually fault codes are stored.

Hi, I had an another forum item where I mentioned an incident with new motor.

The throttle didn't seem to want to respond when fully depressed .It was stinking hot @40 deg ambient outside and I could understand the intercooler not being much use but what else would stop the power when hot & under load. The temp gauge did not indicate any higher than normal temps. Earlier on I would get a bit of black smoke when under full throttle towing accelerating but after the change ex Wollongong I could not even get the black smoke again. Any experience of others with this ??? Help please.

Attempted full throttle towing up a long, steep hill when 40 deg outside - the ecm would be trying to save the engine.

Just an example of how this problem or a similar problem is actually quite common.

I get a very similar result when towing every now and again the same as a few of those posts. Engine Sytem Fault and restricted power, no fault codes stored. Mainly happens when towing my camper up hill or through hilly terrain - mostly if left on cruise control and auto in D. Will happen when not towing on steep long hills - theres one just out of town that I can almost always get it to fault if I try. Best way to avoid it I found is to manualy shift down some gears and hold higher revs and no issues.
