Engine Performance problem
1997 Chevy Blazer 6 cyl Four Wheel Drive Automatic 105000 miles
engine starts and idles fine. When I apply power the engine stumbles and stalls at about 1/3 throttle. Installed new fuel pump (twice), fuel filter, pressure regulator (2000 miles ago). No codes show up. Removed cat converter, no change. Fuel pressure shows 53lb at idle and increases to 60lb when throttle is slowly increased until engine sputters and dies at about 1/3 throttle.
