Customer Question
The motor burnt down...

The motor burnt down. three scored cylinders and 2 cracked heads. While checking it out there wasn't any boost showing. I had tie engine rebuilt,turbos too. When I got it running again still no boost showing. I replaced the air map sensor and the exhaust pressure sensor. it looks like the actuator for the turbos goes to wide open during idle.

Mechanic's Assistant: Which particular sensor are you asking about? And have any trouble codes been triggered?

No trouble codes. The one on the air cleaner

Mechanic's Assistant: What is the model/year of your Ford?

2008 ford f450 with 6.4

Mechanic's Assistant: Are you fixing your F450 yourself? What have you tried so far?

Yes It runs fine at idle, just not mush power . I only drove it around the block once. The two sensor is the only two yet What about the other map sensor?

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

I think it has to be something electrical

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.
