I have told you before that you have to pay for your lack of intelligence
, but it sounds like you are almost as stupid as I am... (I am anxiously waiting for one speeding ticket I collected last week after turning my head to see what all those (approx. 12) people were doing along the highway bending over the guide rail...after the flash I realized they had an excursion to see a radar trap at work...)
drives a 250 Turbo diesel, so I think improper tuning does not cause his problem. Is it a high speed or a high rev problem?
