99 PSD Dies at idle, runs fine up on RPM's

[psdboy]

If my truck is idleing at a stop light it will start to run like it has a huge cam in it, or die! Once it dies I can't get it started unless I wait for it to cool, It doesn't use do it all the time but enough to make me not want to drive it anywhere. Any Ideas?

You have a bias icp sensor or a cps going out. It would help if you could come up w/ a code. Find someone w/ a scanner & capture on demand & continuous codes.

cps sensor cam shaft positioning sensor. is prolly causing your problem.

Being a old post wanting to know if you resolved the problem & what was it? I/m curios. I thought it could have been an ipr circuit short.

Sorry it took me so long to get back to this, but it turns out it was the cps sensor. I went and got a new one with the part # that ends in B so that it only cost 30.38 and that solved it. Works fine now, I have just never seen a cps sensor that wants to work and then quits again.
