This is on my 98 D1.

The plugs and wires are about 10,000 miles old and suddenly now I have to hold down the peddle to get it started. When its running it is fine and the gas milage doesn’t change but if its shut off for more then a hour I have to go through the same thing again.
The only problem I every had with this truck was when I pretended it was a submarine(september)... after cleaning every connection I could find its been running good ever since until this (it hasn’t been off roaded in a month but it has been wet in NJ)

Thanks
Brad

sounds like a injector is leaking down

It could also be a weak fuel pump as well. Check fuel pressure. If pressure checks out ok, I'd start looking into the injectors.

I just had the same problem on my 98 D1. I pulled out the stepper motor (idle bypass valve) and cleaned it with carburator cleaner, and squirted a little cleaner in the plenum before reassembly. The next morning it was running fine and hasn't given me a problem since, 7 days and counting! There are instructions in the tech section here. Good luck.
