1989 Mercury Grand Marquis LS 5.0L Excessive Emissions
This car failed MA state inspection for HC, and CO, it is running great, I cannot seem to get the CO down, I am wondering if the 5.14 volts to sensors could be my issue or maybe the computer grounds are at fault. All replies will be greatly appreciated, thank ...
