2000 E250 van
I have a e250 van with V6 which has service engine soon light on. Light came on after transmission rebuild. Computer says left & right bank to lean. I have replaced oxygen sensors, PVC valve, plug wires and coil pack. I'm getting great gas milage and the engine runs great even with 260+ thousand miles. The problem is at idle and not all the time, the engine acts like it looses 2 cylinders, it has stalled once but acts like it wants to stall when it happens. It does not happen all the time and only at idle once I hit the gas the thing runs perfectly smooth. Any help would be great.
Thanks in advance

OK now I've replaced the IOC and still have the same problem at idle, it actually stalled out on me after IOC was replaced which did not happen before. Seem with each thing replaced the idle problem becomes worse. Whats left to replace?

Why not post in the forum that is FOR full-sized vans? They are much more likely to have a van vac diagram than people here on an F-150 forum.
On the index page here:
Ford Truck Enthusiasts Forums - Ford truck and SUV owners and enthusiasts Community And Information Source.
Go down to the 6th heading "Other Fords", and the 2nd forum under it is "1968 - Present Full Sized Vans". That is where the van people hang out.

Well found a big problem, after taking off the air cleaner and cleaning the air sendor and other stuff I went to start the van and it cranked over and I heard a clunk, stopped and took a look and found the harmonic balancer laying on the frame. The bolt sheared off, NICE
Looked like the bolt had broken off a while ago and luckly the thing waited to fall off while in the drive way of my shop. I'll bet it will run better with the balancer back on and hope that is was the cause of my rough idle but probably not.
