Ok to start I just want to say what a great forum this is. I have a 96 v6 4x4 with 177k miles on the clock. The timing belt was changed at about 109k and the rest of the fluids are all up to date. Since getting the truck 2 months ago I have done the Deck plate mod, ISR mod, new plugs, fuel filter, cleaned the MAF, and throttle body. All the mods and maintenance were done about a week ago and my problem is that I am having major issues with the car stumbling and surging during acceleration. This only occurs around 2nd gear and lower rpms. I have done a ton of searching and research and can't seem to figure out what the problem is. HELP!!!!
