I have a 1999 S-10 pickup, 4 cylinder, 130,000 mileage. I have had new fuel injectors, tune-up, fuel pump pressure tested, and fuel filter. I am still only hitting on 2 cylinders. What could be the problem?

Sounds like you may have a coil pack that went bad, a very common problem on the 2.2, check for spark at the plugs that you say are not firing, if no spark replace both coil packs and the module, some people dont replace both but if one goes bad the other isnt far behind and the module under the coil could have failed, so if no spark replace all three components, if you do have spark check the compression in the cylinders that arent firing
