I have a 97 ram 1500.
Runs fine when the weather is cool, but when the ambient is above 60 it will start up fine and after 5-10 minutes of driving the darn thing wont idle.
TPS????

Also on the way to work today, the oil pressure going down the highway dropped to nothing, until I came to a stop. As soon as I get going again it would drop off again.

Would sure appreciate some advise.
Thanks

Might be the TPS. Are you getting any codes from the computer?

For the oil pressure, I'd think it might be a loose wire or maybe your sending unit.
