Hi All:
I'm helping a friend with a full size Dodge van with a 360 in it. The van will run very rough - dropped cylinders, after it's been running a while. He has put a cap, rotor, wires, plugs in it, and the other day we he threw some injector cleaner in it. The van ran much smoother after add the cleaner, but the next day it was back to dropping cylinders.
What lead us to throw the fuel injector cleaner in the vehicle was that we could unplug injectors and not affect the running of the engine, on several cylinders. After adding the cleaner the engine smoothed out quite nicely. Next day - rough running again.
He has strong spark on all 8.
I'm looking for ideas since I'm not familiar with this engine. I'm curious how many fuel filters there are in this system. Where is the fuel filter(s) located.
We'll welcome any ideas.
Thanks,
-Mike-
