I have a 96 12 valve cummins and when I start it up it is fine. I put It in reverse and press on the accelerator and it reverses fine, then when I take my foot off the accelerator it completely shuts off. What could this be? It's extremely annoying. Thanks

 

Adjust your idle

 

How do you do that?

Would a dealership be able to do it?

 

it takes 3 minutes to do... im sure they would but it is super simple.

 

Okay. Could you tell me what it the best oil to use in the winter?

 

i stay with 15 40.. and i use shell rotella synthetic. but i dont drive my truck in the winter.

 

Okay. I'm gonna be driving it everyday

 

That would mean I would have to drive my car all winter..... sad day
