I have a 95 silverado 2500 4x4 5.7 TBI, with 227000 miles on it. Problem I am having is no bottom end power (no power brake or dead pulling power). I just replaced mufflers, plugs, egr, tps, iac. Truck runs smooth idles great. Code reader will not delete codes of the tps and egr after replacement, however scanner shows all sensors working except for barometric pressure reading stays high and does not change. Map sensor even shows working. Also just ran some seafoam through to clean out carbon as I has a lot of buildup on my EGR.
What could be my problem?
have the same problem?
