Well just spent the day getting a couple of plow trucks running correctly. Two trucks I have are dedicated to plowing our lot and a couple of churches in town. This past winter was kinda rough but not the end of the world. I had been purchasing fuel from the closest station that is 8 miles away. It is a BP and had noticed the increase of alcohol added to the fuel and never really paid any attention to it until today. The fuel was about a month old and neither truck would start. With some tests and scanning the electrical system I had found both trucks failed on the TPS switch. Throttle position sensor. Having to remove the throttle body to replace these switches you would not believe the the gooey build up of sludge. This is the result of 10 percent alcohol mixed in fuel and a vehicle that is just not compatible with this much of mix. This would also explain the lack of power and performance. Looking into this further I now have to rebuild 5 carburetors on the two sleds we have caused by the same problem. I have been working with a few people who are now having the same problems, but much more extreme since they went and purchased the E - 85 fuel which has a 75% higher alcohol content. The alcohol we have in our fuel is causing major problems with many cars and small gas engines for the fact it eats up seals and plastics. So much for our alternate fuel that robs us of power and performance and fuel mileage. What tiny bit we may save will cause us thousands in repairs.
