My friend has a 4/4. He walked in to the gas station and he shut it off. Before that it was running fine. He started right up. It sounded like the starter went. We took it in to get it checked out and it works fine. There is gas in the tank.

When we pull anything or it's just driving down the road you can hear and feel it backfire. It has just started recently.

when the transmission fluid has time to get warm after 5 to 8 miles driving and you stop at a traffic light or something,it shifts great and strong no slipping but want shift to overdrive.

Truck has 320000 miles. All new up front need shop to do this. I hate the smell of rear differential gear oil and wont go near it. Otberwise every thing else new on the truck inluding engine and 4l80E trans rebuild. Call me. Ill come to you.

when the truck is not running you have a good pedal but when you start the truck the pedal goes to the floor what would cause this to happen, thank you daveb

I have only one code PO740

The engine is running.

I am continuing to pop a MIL code of P0102 for MAF sensor low voltage. Performed all voltage and operational checks listed in guide book and everything works as advertized. Replaced MAF sensor twice, but continue to get the code.

What else should I be checking?

I have change both calipers and changed the fluid. When changing the fluid, it appeared more pressure was needed to push the fluid to the right side caliper. Is something in the anti braking system that could be causing this?

this has happened one other time, and of course when a mechanic came it was working fine again . . .

This time i have tried taking it out of 4WD, and into 2Wd. Will not budge. Is this a design flaw?
