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

Yes it has codes stored? Since the engine failed, have you inspected the exhaust system for a restriction?

AlvinC answered a question about my Ford truck that only someone with an in-depth knowledge of his subject would have known what was going on.

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.
