iridiums are garbage

those plugs require a powerful ignition coil to fire them properly

i was getting bad fuel mileage as well , until i switched over to the copper plus plugs

my mileage went up by over 150 km`s to the tank

i get a steady 600 km`s to a tank full now

Many Mass air flow sensors become contaminated with air filter oil from after market air filters that require oiling. It only needs a lttle oil.

Try cleaning tha MAF with the proper cleaner.

the tranny in my 01 went out bc the pump in the trans burnt out, supposedly a gasket broke down and was blocking the flow of the transmission fluid so it took longer for the pump to build up enough pressure to shift. i would be going about 45 mph in first gear and screaming at like 5000 rpms before it would shift to second.

well now i got a question haha, anyone know where i can get o2 sensors cheap? i used to get 25 to 26 mpg and i just drove 165 miles and i have just over a quarter tank left....so basically 13 mpg and i just changed my plugs and wires, (i bought stock motorcraft plugs), had my entire egr system completely replaced 4 months ago, i have a k&n drop in filter, i just cleaned my maf, iac, and throttle body. i have a flowmaster 40 on it right now and i have bfg long trail radials but they are 1 1/2" bigger than stock but it shouldnt matter because they are still street tires, not mud terrains. any ideas beside o2 sensors?

try changing your plugs to something else

i have great mileage with the champion copper plus plugs

you need plugs with built in resistors

change the front o2...autozone has the NGK for $49.99.....thats the best for your truck...i JUST went throught the excat same thing you did...plugs/wires, PULLED upper intake and cleaned out in parts washer...all new purge flow stuff and hoses....truck was still running rich (you could smell it) and using hella gas..replaced front O2 done deal!! the front o2 is what tells computer how hot its running and how much fuel to air to run....when your front 02 gets gunky and worn it will read off one way or the other.
