My e99 had been run on veggie oil prior to me buying it and I believe there is residue in the fuel system. When I ran some WMO through it, at least one of the injectors hung open and the fuel filter almost completely clogged up.

The filter and injectors were replaced last Friday and the truck ran great, until today. It developed a very slight fuel knock and started smoking a bit at idle.

My thoughts are that there must still be some veggie oil residue in the fuel system and I need to get it out. I cannot afford to keep replacing injectors.

Any thoughts, or opinions on something I could use to dissolve and remove any remaining veggie oil?
