FUEL PROBLEM

2004 Chevrolet Silverado • V8 4WD Automatic • 150,000 miles

I HAVE A 2004 CHEVY 5.7 LITER WITH A ENGINE CODE MASS AIR FLOW SENSOR AND MULTIPLE MISS FIRES. CHANGED MASS AIR FLOW SENSOR. STILL RUNNING ROUGH AND RUNNING REAL RICH. ALSO CHANGED 3 OR 4 COILS AND INJECTORS AND STILL THE SAME PROBLEM.

Check it for any air leaks between the MAF and the throttle body.
