Question about 1989 Chevrolet Silverado 2500
You could have a bad fuel pump, do a preasure test on the fule system, If it is out of range at idle idle it up and see how the range is, sometimes the old pumps loose some preasure onthe low end but run fine on top end. recently had this problem with my 89 3/4 ton 2wd

My fathers did the same thing. we soon figured out that the injectors were not making an even mist of fuel they were just dumping the fuel in. we replaced the injectors and the problem was fixed.
