While the Blazer is idling, it runs great. The engine is a Vortec 4.3 High Output with approximately 216,000 miles.
The moment the acceleration pedal is engaged, the engine begins hesitating. It has had all of its belts, hoses, wires, plugs, distributor cap, replaced.
Would love suggestions.
have the same problem?
