My 1995 F250 surges and stalls sometimes . I changed the cam sensor, fuel pump and ipr valve. Didn't fix a thing. Can anyone help?

 

What are the codes?

 

I'm not sure of the codes. The shop coded it for me and told me it was the ipr valve. They put it in for me and $733 dollars later it still did it. So I put a fuel pump in and cam sensor and it still does it. I don't know what to try next.

 

Could you get more specific with the symptoms and what it does before it surges and stalls?

Also, any codes after changing the IPR? (have they been run?)

 

It could be an ICP sensor causing that and I have also seen a trans range sensor do that also. Really need to know what the codes were.

 

Thanks for the help. I will have to wait till Dec 27th so I can talk to the shop about the codes. I didn't write them down because I was sure they fixed it. It ran good for about 2 hous, then I could notice it pulsing or surging again. It even stalled when I came up to a stop sign.

I'm not much of mechanic. I can take stuff apart and put together, but to know exactly what they do is not my specialty. My truck has 340,000 miles on it and I haven't had to do too much to it.

 

Well, if anyone can help ya out, Jon can! Get those codes and go from there -- looks like you've gotten a lot of use outta that truck and has been pretty reliable! Good luck and talk to you after Christmas

 

I'll get the codes thanks alot. Merry Christmas

 

You may want to clean out the screen on the fuel pressure regulator. A friend's 94 was doing something similar, and cleaning out the fuel bowl, changing the filter, and cleaning the fpr screen helped.

 

I changed my fuel filter and noticed that the heater under the filter that the element on it was only hanging on by a thread. I attempted to solder it, would that cause any trouble? The screen on the fpr, where is it?
