with that many miles I would FLUSH the tranny, get the plugs replaced and flush the coolant. To be more specific to your question start with plugs, clean the throttle body and mass airflow sensor. maybe run some seafoam through it too. Just my opinion

Collins846

thanks man and where do u pour the seafoam in at

Right in your gas tank. Add about an ounce per gallon of gas. I usually do this at the end of and oil change because it will thin out your oil. Do this on a couple of tanks and you'll be ready to do your plugs. Read up on that one before you dive into it. There's a sticky on the top of this forum to get you up to speed on that. Good luck.

You should get a tune after playing with your air intake if your truck has the jitters. You'll hear folks talk here quite often that our Ford trucks run a lean air to gas ratio to begin with...your gotts mod simply makes it leaner. And by the way...welcome to the forum!!!

thanks my truck was having that little hesitation before i did anything to it but once i put my chip on it dont have it ..my next question is im gettin ready to order a leveling kit from rough county should i get just the front 2.5 for 99 bucks or the front and back blocks that are 1in for 199 as a kit or is the back even worth doin ?

Lieutenant G

Depends on if it us 2x4 or 4x4. 2x4 will need the added lift in the rear with a 2.5. 4x4 will not.

Collins846

its a 4x4 so i should just get the front done then and what size 2.5 or 3 and what are some size tires what would look good on it i am using the stock rims

Most folks will lean towards the 2.5 level (I did) due to control arm problems and blah, blah, blah. Others say that there's no harm. Better safe than sorry for .5" difference if u ask me. 35's should fit nicely!
