Engine Power problem

[invader166]

Check the air filter and air intake system!

I had this happen to one of the engines I use at work one time. Symptoms were similar. Lack of power at open throttle.

The cause was an air filter that was sucked in the intake, blocking airflow to the turbo inlet.

Donno what kind of turbo set-up you have, but i think something like that can happen when you use junky filters, or when the filter becomes wet.

Definitly check that first I would think.
