Analog meter. Digital meter just won't work. Return voltage should go from less than one volt at closed throttle, to greater than 3.5 volts at WOT. Progression should be perfectly smooth, no bouncing around at all. It also needs to react as soon as the throttle blades start moving.

 

Ok. I'm gonna check this tomo and check in..

 

You can use a digital but it has to have a bar graph witch most meters don't have.

 

Ok just checked the tps. And it does exactly what it's suppose to. Gradually climbs. To just about 4 volts. And it starts climbing the moment you mess with the throttle.

 

Is the shaft it rides on worn? Installed properly?

 

Ok. Since last post. Ive changed the charcoal canister cause it was so bad. The particals would fall out of it. And I fixed a fuel leak it had. But still no clue what's cause the truck to have these issues.

 

Yes. I've double checked that it was installed properly. Even took it off. And double checked

 

I think you are going to need to plug in, and see what the PCM thinks is going on..... Can you read live data?

 

I would put a gauge on the fuel rail just to see if it has constant pressure. Other than that you need to see what's causing the pcm to change things. During this time has it thrown any codes? Is the check engine light working? You can do the key dance to retrieve any codes.

Ok. Installed new computer.. didn't make a difference ligit at a loss on this one. I have no clue what's causing this truck to have these symptoms. I have checked the fuel pressure it's constant 49. I have a basic obd scanner. But doesnt read live data. I'm hoping to get one soon. I just don't know what could cause shifting issues like this and stalling like it does.
