All the help is more than welcome :)
I really think it´s the engine, transmission is repaired about year ago and when that thing occurs at idle eng is shaking bit more that usual and sounds bit odd...
4x4 not by accident :) Faun clutch may be... Today I drowe 30 km to near by city and back, didn´t work. When we came back home, I ate, changed spark plugs to my wifes Blazer and after that I started truck and it worked fine again!?
When that sound comes on engine loses power, what does that??? Sometimes louden and sometimes less. Occationaly it´s workin just fine when that sound is not present...
I took belt off and all accessories pulleys are rolling freely.Turbo is ok.
Noise is new, I´ve had thos truck for 2 years and it started few weeks ago. Feels kind it´s looseng power when this sound comes in but not sure... Could there be something powerloss relating to that sound...?
Yes I´m...
Truck is -95. And yes I mean 1 bar boost (14,5psi) and it maxes about 17,4 psi. But when earlier tested with scanner aboard the SES came on with less acceleration that 10 sec :S
I´m wondering now why SES light doesn´t come on when boost rises above 1bar?
When I put turbomaster on and drowe with scanner hooked up it turned light on at 0,9-1,0bar.
After I installed that adjustable pmd resistor switch it haven´t come on anymore even at 1,2 bar??? It´s now at setting #9...
