Remove the air cleaner and start the engine. Watch how the fuel injectors spray. It should be very fine, almost hard to see. I had a similar problem on my first truck, 91 GMC Sonoma w/2.5, it only had one fuel injector. It fouled plugs in about 1k miles and it really sucked down the gas. The fuel injector was spraying on one side and just had gas running out on the other. Bought a reman injector and some new plugs, problem solved.
