Engine Performance problem
2003 Chevy Silverado V8 Four Wheel Drive Automatic 90,800 miles
The truck starts fine but when I try to punch it down in the city or try and take it on the highway the truck is really sluggish and the engine light comes on. I had it analyzed and it said check Mass Air Flow sensor as well as irregular cylinder fire. I started by replacing the spark plugs and wires then I replaced the fuel filter and finally the MAF sensor. What next? Could it be the fuel pressure regulator? Thanks, Gary
have the same problem?
