A Maf and Vaf are one and the same. However, the P0303 is not a MAF sensor DTC error code. It is a misfire detected on Cylinder #3.

You may need new spark plugs and/or wires or have a clogged/defective fuel injector on cylinder #3.

BTW - Stick with the AC Delco OEM Platinum or Iridium spark plugs to include ignition wires. Whatever you do, do not use Bosch spark plugs.

yes i found out to late about the bosch plugs. ill take them out ty

Bob-your right on that one. Use ac delco. I used bosh o2 sencer once, and my car did not like it at all, then i used ac delco, works great. i like ac delco anyways.
