Question about 2000 Chevrolet Blazer
When I reach speed of 45 mph to 50 mph the car starts to run rough - when I put on diagnostic machine the engine shows no sign of problem with injectors or plugs. when i engage cruise control at 50 mph it smooths out.
O.k... question... when you punch it... does the car barely go... and the engine reve up? if you gently press the gas... does is act the way it's suppose to? if that's what you have... change out the fuel pressure regulator... and the fuel injector... see if that doesn't work for you... o.k... good luck to you
