I bought a 96 250 today, and it has a really rough idle. I think its a fuel issue but i wanted your input. It idles rough and is a really choppy idle. It does it from start up until shut down. The truck seems a little underpowered but i can feel the turbo kick in. I was going to check the ful pressure today but broke my fuel press. gauge. I think its a week lift pump. Just wanted to see if you guys had any ideas on things to check before i go buy a lift pump. I had the truck idling and pulled the icp and it did not change and the cel came on. Iturned the truck off and plugged icp back in and the check engine light was gone. Any ideas? By the way the truck is a standard and stock except for a straight pipe.
