Independence Day Special - Part 2: Ford F150 "Runs Like Crap"

So replacing the spark plugs and properly reconnecting the EGR vacuum control lines made the old Ford run much better. But we are NOT done...it s now back to a single-cylinder misfire!! I perform one last test to pinpoint the final problem. Repairs and verification included as well :) OTC INJECTOR PULSER: https://www.amazon.com/dp/B0002SR5OO/?ref=exp_pinehollowautodiagnostics_dp_vv_d Enjoy! Ivan
