93turbo_animal said:I know of 4 OBS that when you rev it up it has a cough to it and I'm sure that theres nothin wrong with at least three of them and I read countless post about it from new truck owners cause it will smoke a little when it does it and they think somethings wrong I guess you got the one of the odd balls that don't or your talking about running at 2200 rpms and I meant just reving it up
first off a skip/miss ina psd is not normal.this is usually caused by bad injector O rings.it might nedd an oil change.the wrong type of oil could have been used in it.another issue with the 94-97 trucks is that they had the wrong dipstick for the oil.some had a dipstick that read full around 10-12 quarts when it takes 14 quarts.aerated oil will cause a skip.
im also willing to bet that on these 4 OBS you speak of have probably never had the fuel pressure regulator screen changed.smokeing associated with a skip is also caused by bad injector O rings.

now if youre considering an SD you have to be completely honest about what you plan to do with the truck as far as added power cuz there are a few years to stay away from.
