lacks power and smokey
 

A week ago i had my injection pumped replaced. My car runs on veggy which im sure is why it messed in the first place. I think i had bad oil in the tank cause i used it for an hour after it was running fantastic. Then it messed again, the injectors dont seem to clogged cause it goes. Its def. turtles though and there is a bunch of smoke that comes out. ive ran some diesel kleen trough it, i also came from freezing weather where it got fixed to now warm weather. i feel it could be the injector timing but im not to sure. any suggestions will be appriecated.

Start off by getting your Fuel Tank Cleaned and the Filter Screen in the bottom of the Tank cleaned. change the Primary (plastic) and Seconday (spin-on) Filters.
Fill the Tank with Diesel Fuel and see what happens.

If it runs OK like that just continue to use only Diesel Fuel or learn how to turn the veggie into Bio Diesel.

I had the same problem. Cleaned the tank and replaced the filters. Ran like new.
