Ok I have a friend with a small problem with his 97 250. He said it stalls when you let off the pedal or let it sit and idle for a cpl minutes. It will run like a scalded dog as long as your foot is on the pedal. Any suggestions

Thanks Tom

 

Sounds like the cam position sensor.

 

Thanks he said when it dies he can turn the key and it fire right back up.

 

Ok I talked with him yesterday. He replaced the cam position sensor it has been doin ok then the other day it died again while sitting at idle in park. He called the dealer and the guy said to check in tank filter. Well the filters were shot. He replaced the filters and it is still cutting off. Please help

 

ck the valve cover gaskets my 97 did the same thing and i replaced the valve cover gaskets and found that one of the plugs was melted replace now truck runs great

 

My truck, when it sits in park and idles for an extended period of time, tries dying when I go to put it in park. If I blip the throttle on the truck before I put it in drive, it wont stall.

 

check the throttle position switch and idle validation switch, both located on the throttle pedle.
