rough running van

I hope someone on here can help. I have an e-150 conversion van with the 5.8 (351 clev) engine. I made a round trip of aprox. 220 miles and went through

20 gallons of gas. The problem started about 20 miles into the trip, bad idle, lots of black smoke, stumbling @part throttle. Check engine light did not come on. Fuel filter was changed about 400 miles ago, just checked air filter before trip and looked just like new (has about 1k on it), oil and filter was changed about 800 miles ago. Total miles is 129k. Thank You

No, you don't. It's a 351W (Windsor).

Sounds like leaking fuel injector(s). Get it on a scope, or at least check your plugs to pin it down.

could also be bad fuel pressure regulator

Remove the tube from the fuel pressure regulator to intake, check for gas presence.

Usually on the Injector fuel rail, It's sort of a "can shape" about 2 inches dia by 1.5 high... nipple to soft 1/4 inch hose to intake behind (as the air flows) throttle body

I pulled the plugs yesterday, and they were fouled and worn down, champions btw. Then I checked the cap and rotor, The cantacts was worn and pitted. I am replacing these today, that should help alot. The new plugs are Bosch and the cap and rotor are BWDs with lifetime warranty and brass contacts. I hope this helps alot, as I am on a limited income. Thanks for all the info Guys!

What year van is this? You?re wasting your time by replacing the plugs as well as the cap and rotor if you haven?t resolved fuel system problem. The plugs will just foul out again and the cap & rotor will have no effect on your problem. Check the fuel pressure regulator for fuel in the vacuum hose as suggested. If you find no fuel in the vacuum hose, have the fuel pressure checked with a fuel pressure gauge and have the trouble codes checked. You may have excessive fuel pressure or a sensor circuit problem.

P.S. take the Bosch plugs back and get Autolite or MotorCraft.

Why take the Bosch plugs back? I always had gl with them. As with the cap and rotor, they needed to be replaced as the contacts was worn and pitted. I do have fuel present at the vacuum line. Now how do I remove it? There is no apparent way to remove the fuel lines. Again thanks to all the suggestions! Mark

Replacing the cap & rotor may be good maintenance but it will not correct your current problem. Use the Bosch plugs if you want to, I?ve just seen too many drivability problems caused by them. I have to warranty all of the work I do so I use parts I can trust.

What I need to know is how to remove the lins as there is no apparent way to remove them. Thanks! Mark

A special tool is needed to release the spring coupler. It's a fairly cheap tool but you don't need to remove the fuel lines to replace the regulator. Just remove the 3 screws from the bottom of the regulator and lift it off. Bob
