I have a73 Corvette with a 2002 LS1. I installed a 5 wire Maf sensor. I keep getting a code P101 and sometime it the engine seems to kind of a burp when driving down the road. I changed the Maf sensor and ordered a new harness that is for the 5 wire sensor .Is the tune different for a 3 wire to a 5wire sensor ? Anybody have the answer? Thanks Charlie.
