MAF problem I think? I have a 2000 ws6. I keep getting rear O2 sensor low voltage problem. A couple of people told me that it was the cats but I took it in to a chevy dealer and they told me that the fuel pump was going bad. I changed out the fuel pump myself and it is still having the same issue. The issue is that the car gets very sluggish when I step on the gas. I went to Autozone and one of the guys told me to unplug my MAF and see what happens. I did that and the car felt like it came to life. Has anyone else had this problem and if I leave it unplugged am I going to hurt the engine? What would you recommend for a replacement if it is the MAF? Thanks
go back to Autozone and get a maf cleaner spray. Take the maf off of the vehicle and fully clean it with the spray. Once it's completely dried put it back on and see how it does. If u unplug the maf the car goes into limp home mode. So more power is to be had with a properly working maf.
