    Ooohh, boy. Doh! Problems already?

    Check the back of the brake petel for the cruise issue. There is a plunger back there that has to be hit. On mine the braket that holds the plunger had been bent over the years. Easy fix. On the adjustable petels, the most common issue with that is the gears inside the assy the plastic gear...

    Power issue 03 5.4

    COP is another name for coil packs? I will check them out tonight. I have actually already clean a mass air flow sensor. My only question about the coil pack is if they were the cause of the problem when the truck does act up wouldnt the engine shake? Sent from my DROID BIONIC using Tapatalk

    Power issue 03 5.4

    I tried posting this a few months back and no 1 has any ideas so I am going to try again. I have a 2003 ford expedition XLT 5.4. Over the course of the last year I have been experiencing some power issues. I noticed the power issue the most when I am pulling a load. It's hard to properly...

    Screwed up o2 sensor can screw with your MPG too. I have had one that was not tripping the check engine light but was not reporting correctly and gave me terrible performance and MPG in warm temps but was fine in cold temps.

    beyond gas draining [READ]

    I agree with betro. Check the float on the pump. Mine was acting up and I pulled out the pump and the float had a little bit of an issue moving up and down. I just cleaned it up with a little bit of steel wool and then it was fine. Sent from my DROID BIONIC using Tapatalk

    2005 Ball Joints bad.. Advice?

    Assuming u have the tools to do it just get the truck in the air and go for it. Since u have the experience with the other truck it should b easy. The suspension is fairly similar. I have not personally done the ball joints on this truck so no input there. One thing to keep in mind is you...

    Rear Window Washer Not Working

    You have to remove the two rear pillars and the two middle ones and the two or three push pins (whatever they are call) to remove the headliner enough to get to it. Its in between the headliner and the top of the truck at the very back. Its pretty small from what i remember maybe 3 or 4 inches...

    Tuner question????

    Superchips :-). I use it on my 03 and it works great on top of that i use ScanXL Pro and an OBDII Bluetooth adapter to really dig in deep. Either way you go its worth it.

    Rear Window Washer Not Working

    Do you hear the rear pump working? You should be able to hear it, i know i can hear mine plain and clear. My guess is its the rear wiper pump.

    Tire Noise When Turning On Dry Pavement In 2 Wheel Drive

    Have the front dif inspected. Sounds like it may be engaging and creating drag. Just a guess but i bet it does have something to do with the front end of the 4wd system. I know if i have mine in 4wd and make a tight turn the front diff will lock and i cant move until i straiten the...

    03 expy 5.4 o2 sensor question

    I have been having power issues on my expy for a while now and I think I have narrowed it down to the o2 sensor by using a obd2 software. One of the sensors is staying around .62v. Anyway I need to try to replace it. However its the on on the passenger side on the manifold. HOW THE HELL DO U...

    Loosing Power at low RPM.

    Would this theory also hold true if i was maintaining 70 mph? Just want to make sure before i start buy alot of new parts.

    Loosing Power at low RPM.

    Ok, filter is fine. However i have noticed something. I took the truck on a 900 mile round trip and it seemed that when the temp got higher i had more problems. I left around 12pm and all most the entire way there i was having power delivery issues. Downshifting not only into od but also...

    Loosing Power at low RPM.

    OK great ill check out the fuel filter. Not sure how to check the coil packs. if i remember correctly you have to check resistance from the pack right? anyone know the proper way?

    Loosing Power at low RPM.

    changed plugs fuel filter about 30k miles ago. Mine is a 2003 Expy XLT 4wd with the 5.4 motor. Never have changed out the coils at all. But i would think if it was a coil that the engine would shake and it would throw a code. However its smooth acceleration.

    Loosing Power at low RPM.

    Hello all, i have been noticing that my truck has started to loose power at lower RPM's (1000-2000). Sometimes i will take off from a dead stop and just will have no power. Then it gets up to about 1800 rpm or so and starts to act normal. But it does not do this all the time. Now about 6...

    I just installed a flowmaster system and its a 3" pipes all the way back. Mine is the 03 5.4L 4x4. Sounds like your exhaust man is being lazy or something.
