When accelerating in my 96 5 speed tracker it sputters the whole time. keeps sputtering even at cruising speeds it still sputters when i hit the gas.

low jet is dirty

Check cap, rotor and wires. Also possible is a cracked distributor housing.

When you say "sputters at 2000 rpm" , are you referring to ANY time the engine is at 2000 rpm - meaning in Park, when you are just goosing the throttle, or in gear when you are accelerating, or at highway speed in high gear? If you are experiencing a "shuddering" in the engine at certain speeds/rpms - especially if these are speeds you regularly cruise at (long commutes at steady speeds), the problem could be in the Throttle Position Sensor (TPS). They have a tendency to wear unevenly if you drive a certain steady speeds. Eventually, the problem would progress to an engine code, but it may occur without setting the check engine light.

Check for fuel supply problems as it sounds that at sustained high speed the fuel supply is not good enough. Possible pump dosen't have enough capacity

Sounds like your Idle Air Control valve is bad. The IAC valve controls the engine idle speed. The valve is located on the side of the throttle body. This valve allows the necessary amount of air, as determined by the (PCM) and controlled by a duty cycle signal, to bypass the throttle plate in order to maintain the proper idle speed. Good luck!

have you had you fuel system cleaned? meaning had your injector cleaned?

to funny, My car an 07 equinox with 52000 miles on it just today started sputtering. I googled equinox sputtering and I came up with this sight reporting the same exact problem-- help

sounds like you have an ignition missfire, have it put on an analyzer to determine the cause.

sounds like the ignition module is going bad.

loose vacuum line, check for same, also check the map sensor and the measure the fuel pressure, make sure its at spec
