I have disconnected the MAF. I have not driven it disconnected. I did notice a dip in rpms when unplugging and then replugging the MAF. The MAP sensor is the trouble code though and the socket has been tested and has the 5 volts required. I have checked fuses and relays. In the electrical box in the engine bay there are a few relays that have light brownish marks on the sides that looks to be maybe due to excessive heat Is this normal or should i start checking around that area? Note burning plastic smell does not iminate from this area.
