had been running my car on E85 for approx 6 months.
Initially, the engine was occasionally cutting out, especially in 2nd gear, once over 6000 revs.
2 weeks ago, the engine started cutting out lower and lower in the rev range. Eventually I couldn't go beyond 4000 revs.
The fuel filter on the new Sard fuel pump (installed in the fuel tank at the time of the conversion to E85) was covered in brown, slimy stuff.
That was cleaned up and car runs with no probs now. Furthermore, the car idles a lot quieter and smoother (even with the air con on).
Anyone expirienced something similar?
I'm aware that ethanol is very good at cleaning stuff well; wonder if all the grot was in the fuel tank from before and ethanol has cleaned it off the walls of the fuel tank.
