1st, we found a bad 02 sensor that wasnt lighting the ses, still had zero Gs acceleration , with a miss on acceleration , and idle -14 MPG all the time- seen all the blogs about air pressure assistd pro cleaning the injectors, so started dumping the bottles of kerosene in the tank - voila- finally cleaned the stuck injector(s), now smooth as silk, 2-3 years ive been chasing this problem, will have to add a bottle to this truck often-very finicky injector setup -1994 4.3 S10
Just some quick checks: I'll assume you haven't received any error codes.
fuel filter,bad gas(water in the gas), indication of failing fuel pump(the 4.3 is notorious for its pump problems),dirty spark plugs, clogged fuel injectors, failed fuel injectors, MAF malfuntion(mass airflow sensor), I could go on...
