Default Jerky acceleration

I just changed the oil, tranny fluid, rear diff fluid, oil filter, air filter, spark plugs (and gapped them). Breaks, and i had the rear wheel bearings and axle replaced. and I'm noticing my acceleration is jerky.

I have always used the highest grade fuel, and I even put the fuel cleaner in three times of the last three months. and it's still jerky in all my gears when i give it some gas. If i'm light on the peddle it doesn't get jerky. but if i accelerate anything over light in any gear. it's jerky. any ideas?

I bet you have a bad plug wire.Had it happen in my car same thing. Even if they're new wires you can get a bad one.

Start the car and pop the hood to see if one's arching out on you.

Kind of a dumb question but do you have a stock H pipe on the car? Looks like the list doesnt include the fuel filter change. It might be a shortage of fuel to the motor. Porbably a clogged filter. THose things gota be changed every 10-12K for maintance.

boots/wires and Clogged cats are both great places to start. The fuel filter is up for debate on if it's going to create jerky acceleration, especially if the issue is only at take off. Always start with the cheapest things first.

so it is my intake manifold. but it looks like it's leaking out the gasket.... i don't think it's cracked. but it's more jerky than ever so it's getting worse. looks like the gasket though.

Anyone know how hard the gasket or intake is to change on a 97 gt?
