About your vehicle.
You will want to check the fuel pressure to see if it is too low. Also that the filter is not restricting the flow of fuel.
Then, the exhaust may be a little bit restricted. You can have a back pressure test done on it at most exhaust shops to see if the cat is clogged.
If they are both ok, then you will want to take a sample of the fuel to be sure that it’s not contaminated.
checked all that need a different try.
this was done at a shop it runs fine at park idling and reving . it seems to run ok on flat ground but studders going up hills. injectors have been checked
The truck will not hold speed but at times it will. I don't think they checked the mas. Its a bucking rev cutout rev cutout.
I have cleaned the mas and it didn't change a thing. I also removed the connector to the mas and the truck barely kept running, Any other advice it seems that I can't find a fix to my problem..
yes there was, it almost stalled out.
