Subject: Re: Why is my  car running so rich? C900

Setting the AMM to 380 is not the correct procedure. Read the o2 sensor and set the AMM according to its response to get an average of 0.5V at the o2 sensor. If it is dead, or the fuse blown, or not connected, this could cause your problem. Check these next. KeithG Mike P wrote: > My car - 1984 T16 - appears to be running rich.
