My 96 S-10 with a 2.2 started bucking and sometimes I'll even hear a little back fire , can't tell if it's back firing out the intake or exhaust though. Runs fine until about 3rd. gear and then it starts acting up . Computers not throwing any codes . I'm thinking fuel pump, fuel injector maybe even plug wires . Changed fuel filter , no difference. Thought maybe some one out there had a similar problem and could help me narrow it down.. Thanks.....

2.2 in an S-10? 1996?
I don't know...
But if the engine goes pop-pop-pop (etc) on acceleration; It might just be, maybe, a worn camshaft. Is it a V6 cylinder? 2.8L?
The poor performance and popping sound sounds like a worn camshaft (to me)... but a full tune-up with disturber cap, rotor, wires and spark plugs, never hurts.
Best wishes, Dave
