My car seems well mechanically other than (I believe) a dirty/corroded fuel tank, where sometimes the fuel supply (accelerator) is weak.
What can be wrong? |
What were the actual MPG figures both before and after, could you actually get exactly the same MPG on the same route or tank to tank ? I ask because a 1 MPG difference seems within any margin of error to me. I'm probably not the most precise around here but I think any tank to tank with a difference of under 3 is probably no change at all.
I'm interested in the techniques you may use though, I have switched from a TDi to a small petrol car and the pulses take a lot longer than they did. I used to be able to go from 60-80 in about 3-4 seconds. Now I don't go much above 65 and it takes a good 5-10 second pulse to get there.
Also do you have any other mods, e.g. tyre pressures higher or aero mods / deletes.
