hi i have been pulling my hair out with this problem on my 99 jimmy 4x4 sometimes for the past year when tring to pass or sometimes from a stop i get a loss of power between say 2800 and 3800 rpm it doesnt miss just momentary loss of power i have replaced all the obvious stuff fuel filter, plugs, wires, cap, plugs, o2 sensors all of them and replaced upper intake gasket and tb gasket.it has only thrown a code once when it was acting up i really kept reaming it while it was doing it and i threw lean bank one and lean bank two but that was a year ago and no codes since this is really strange this may help sometimes it is worse after i reverse in one direction then take off in another. sometimes if i start the drive just for a minute then shut off for a minute then go to pull out and hit the gas it does it. sometimes it doesnt do it at all but when i need to pass it does it. the fuel mileage is good i am completley stumped on this one thanks for your time and your service to all us diyers out here.
