yes you have a clooged injector. you can try running a bunch of cleaner through it. also could be the iat sensor(intake air temp) if you put an aftermarket intake on make sure u use the iat on the new duct work. id do the cleaner and the iat sensor and that should be good also check for other vacume leaks from hoses and from egr valve

Cant find the iat sensor on 91 s10

The IAT or MAT sensor (as equipped), is a thermistor (resistor which changes value based on temperature) mounted either in the air intake snorkel or the manifold (depending on the application).
