My Tahoe is sputtering when you give it gas. If you give it slow when it is in park it revs up just fine. If you try to rev it fast then it bogs down. When it is in drive the engine shakes and it gets a lot worse on the bogging down. I changed the plugs and plug wires and also the fuel filter but that did nothing, any suggestions?

Problem solved! I changed the dist. cap and rotor button and she runs like a scalded dog. I guess when the platinum plugs go out they take everything with them. I had the truck in at 100,000 miles and the the plugs showed no wear at all. It now has 203,700 miles and they look like they had been run for three times as long. The gap was out to .075 and some were .083. They should be .060. It is a Vortec 5.7 V8. Thanks for all the posts and glad I found you all.
