Hello, I am looking for the intake manifold hose diagram for my 1998 B 1500 5.2 L, V8. Can anyone help me. I've been broke down for a week now. I know the problem is within the fuel, air intake and there is a vacuum leak somewhere. I replaced a couple sections of smaller hose line that was brittle but I'm not sure I hooked them back up properly. If anybody has this diagram please send. Thank you.

 

What symptoms are you experiencing? A vacuum leak shouldn't completely disable your van.....

 

When I turn it o er it almost seems like its not getting gas. Its also sucking in a lot of air near the IAC into the throttle body. Almost like its drowning or hissing. I can't really explain it. Every so often it will start but as soon as I hit the gas petal it dies. I just changed the clil about a month or so ago. I had pretty much the same symptoms and I hear that these vans are known for problems with the coil pack. Is that true?

I also have a couple of hoses I. Not sure are hooked up correctly. Which is why i need the diagram if anyone has it.

Thank you for responding. I am totally lost at this point.

 

After taking the throttle body off. I'm seeing the inside of my intake manifold and its really wet inside. There's a bunch of little black flakes at the bottom of it also.

 

Plenum gasket it blown. Common problem with these. Make it run first, then fix the plenum. (two-piece intake, there is a steel plate with a gasket on the bottom. Gotta pull the intake to fix it.)

Check your fuel pressure.

 

this is sage advice
