I have a 1989 chevy s-10 blazer 4.3L. ,,it has been sitting in a garage for 8 years . I changed out the old gas ,, but when I start it ,,it has a real rough idle ,,when I put it into gear it's even worse
Did you change the oil and filter, check for vacuum leaks, pull the plugs, inspect the wires, dist. cap and rotor?
I'd check the injectors.
