Mechanical problems with delivery van

So, you don't have a check engine light on; that is good news.

Because your runner valve seals/gaskets are not causing the problem.   If they leak, there will be unmeasured air getting into the combustion chamber and that will throw the light.

Now, it doesn't sound as serious.

Go to DIY.com. It's also a service of Autozone that you can buy a subscription through. It's around $20 per vehicle , but it gives you access to factory manuals and factory troubleshooting that only the Ford dealers will have. It blows Haynes/chilton manuals out of the water. You'll have access to all the info you'll need to track down the problem with correct diagnosis and not guessing to what it is.
