RE: 2003 Workhorse W22 running horrible
Looking at those code, I get that you have a electrical issue along with fuel system. Most of those codes are generic so not the issue. You did not state on the battery charge as in full 12.8 volts. Did you recalibrate the new pedal assembly. A lot of thing go South when something set sometimes.
First you need to check fuel, air and spark. Throwing parts at generic codes will cost you a lot of time and money. The smoke is either water or oil which could be several thing. Too much fuel can cause a lot of smoke issues.
The battery was charged prior to any attempt to start. Also, I didn't know you had to calibrate a hew pedal assembly. I will look into the process. thank you.

RE: 2003 Workhorse W22 running horrible
Sorry I didn't get back to you all sooner. I appreciate all the input I can get. I can't get to work on the rig until this coming weekends. I will check all the areas you suggested and let everyone know. I followed the fuel lines all the way to the fuel rail and couldn't find any leak for the life of me. I got to a point where it had to be coming from inside the manifold. I hope I am wrong and your advice points me to the real culprit.
What was odd was that on the first start it was almost a steady steam of fuel, it was leaking so fast. When I started it the second time, after about 30 minute wait, it almost didn't leak at all. Well, it was just not coming out the exhaust flange, I didn't check the exhaust connections any further back.

2003 Workhorse W22 running horrible
I am trying to fix my father's Winnebago 35U, based on a W22 chassis with the 8.1 Chevy motor. When he purchased it used it ran great. It sat for a year and has now developed a very rough idle, to a point where you have to stay on the gas to keep it running. I had a mechanic look at it and it had codes for P0107, P0120, P0220, P1516, and P2135. We have replaced the TAC, the pedal assembly (with the correct p/n from Ultra RV), the MAF sensor, MAP sensor, plugs and wires. I have also cleaned the throttle body.
If it sits for a day or longer, it will start and run reasonably smooth, but blows a lot of smoke out the driver side exhaust. It had recently started leaking fuel that slowly dripped on the ground directly under the oil filter. When I started it today it was almost a steady flow of fuel leaking in the same spot. I shut it down to get a better look, but could not identify where the leak originated from. After scratching my head for an hour, I fired it back up (she didn't want to start) and the fuel leak had almost disappeared. I could see a small amount of fuel pooling up on the drivers side exhaust manifold bolts. I pulled the first plug on the drivers bank, from the inside looking forward, and it was soaked in fuel.
After a little research I found that some people were experiencing the same problems due to a problem with the fuel dampener failing. Has anyone else experienced these same problems, or can point me in a better direction. I appreciate any help!
