Default Re: 2.5L sputters while accelerating

Either you have a spark problem or an injector problem. The quickest and cheapest fix is to try a couple of bottles of fuel system cleaner. Pour a bottle in and fill the tank. Run the tank damn near empty and repeat. I like Chevron Techton (up to 20 gallons bottle), others like seafoam.

The advantage with seafoam is that you can suck 1/3 of the bottle into the intake through the vaccum line going to the brake booster on the master cylinder and put another 1/3 into the tank, thus cleaning both sides of the fuel system.

If neither of them work, take a look at your spark plugs and wires. If they check out, your distribution boxes that the spark plug wires connect to.

Let me know if any of this helps.
