Alright 2001 impala with the 3.8l v6. For quite some time the car has been running terrible and I finally decided to tinker with it. So I just changed out the fuel pressure regulator because the vacuum line going to it smelled like raw gas. It helped the car run a little better but it still runs bad.

So I re scanned the car for codes and got the p0102, p0443, and the bank 1 sensor 2 heater circuit malfunction. I recently replaced the maf with a jy unit to try and fix the p0102 code to no avail. I also fixed the first 4 inches of maf wire on the pigtail end to no avail. So while I was tinkering with the car today I found that one of the wires in one of the "wire blocks" was not even remotely connected to the block. So while the car was running I stuck it in and after a few seconds the car died. So I went ahead and did the maf test and unplugged the maf while leaving that one wire plugged in and wala the car stayed running, horribly but it ran.

So question is....could it just be that there is another break in the wiring I should chase down or could this maf be bad as well? Will upload pictures soon
