My 94 s-10 2.2L is cutting out almost like missing when trying to maintain constant speed. i just did a full tune-up except for fuel filter, changed o2 sensor, and throttle position sensor. this problem is boggeling the **** outta me If u have any comments or suggestions please feel free to leave them thanks for your help.........

 

This thread is sorta old, don't know if ya solved the problem yet or not, but I would change the filter, was it doing this before you tuned it up?
