Finally today it did the same thing and then wouldn't turn on(would crank but not start). When the tow truck arrived I was able to start it again but still spuddering. When I got it home I took out the mass flow meter and cleaned it, now it starts right up sounds good but when I drive it it drives fine till I get on it. When I hit the gas hard it revs, sputters and doesn't go anywere. Any Ideas? Maybe a bad mass flow? I've installed new Accel coils and spark plugs a little while back so don't think its a coil problem.

A tuner is needed and will aid in performance, but will not help extend the life of the transmission. Just my opinion, based on what I have seen happen to others. These transmissions are not the strongest component of these trucks, to start with.

Dont abuse your truck and you will be fine. i just dropped $2424.13 on a new tranny in my truck, i was abusing it and it had 130k miles. idk, life lesson.

Honestly my favorite mod was the hid's from www.DDMtuning.com and the two hellas behind my grill with hid's. Makes for a sexy combo and should cost around 200 bucks.

Best advice, save your money. Im still in high school, work two part time jobs, gave up being a kid to have nice toys. Its not all that great.

Oh heck - why stop there? Oil filter reuse: "Works good, just hose it out and dry it off."
