Just got f-150 4x4 4.6L ,5spd , coughs and sputters a bit on acceleration ( worst when motor is cold) very poor fuel economy .... any suggestions?/ complete tune-up maybe?
I've had chevy's until now so I'm not to familiar with the f-150 , any tips where to start to improve fuel mileage would really help

 

How many miles are on it? I would say a complete tune up is a good place to start for sure. Is there a check engine light on?

 

What year is it?

 

I would do a can of SeaFoam or Deep creep.

then replace the plugs, wires, etc. clean air filter or even get a cold air intake kit. you can pull the mechanical off the engine and install dual electric fans (removes rotating mass from the engine = more power) or for $400 get a programmer and give your truck a new life.

 

its a 2001, just gave it a complete tune -up, seems to be alot happier now , Cheers

 

it's got 65,000 mlies, no engine light on...... I just gave it a complete tune-up ......wow! what a difference, the plugs were filthy (looked original) but ya it performs a lot better now .....Thanks for the tip!

 

Good deal. It's amazing what a tune up will do. That's some low mileage for an 01'. Must not drive it very often?
