Anonymous, MN (2006 Ford F-150 Unsure 5.4-L V8)"So I bid on this truck, it was a government vehicle, specifically a town and I already knew that it had problems when I bought it, but I got a good deal. Did research on YouTube and sure enough it had to have the intake manifold, gaskets replaced due to leaking antifreeze across the top of the motor and dripping down into each Spark plug hole, causing misfires. so that definitely was part of the problem, but still over the last year and a half or so have had repeatedly on and off misfires and have changed several oxygen sensors and that has seemed to help greatly but still occasionally get a P2198 front driver side oxygen sensor code and a burning rich code, have replaced the injectors, the fuel tank was in bad shape. the fuel was horrible looking so its possible that theyre just plugged up again, on the advice of a friend Ive started using ethanol free gasoline, which is a dollar a gallon more and Ive come across something from Lucas oil, a green liquid you add 1 ounce for every 5 gallons of gasoline to help counteract the effects of ethanol on older vehicles and that seems to be helping some, overall the 4.6 L is a pretty good engine, the 5.4 L which closely resembles it is a pretty bad engine from what I understand. The oxygen sensors on this vehicle are heated oxygen sensors and as a result, they are too warm up to help on cold weather days to get things working quickly, and one of mine had a direct code that it failed in the heater wire, which on this vehicle, there are four wires per oxygen sensor one of them runs the heater wire, when I changed that to the correct oxygen sensor things really improved. Also, I had to replace the mass airflow sensor MAF because it was faulty and that greatly improve the power and fuel mileage"
