    What does a loose spark plug sound like?

    Bang on. What he said.

    Constant misfire #3

    Oh, and your cats are probably blocked solid. Once I fixed that everything got much better.

    Constant misfire #3

    Not sure if an injector could cause that. I'd replace all plugs on that cylinder bank. Especially 4. It can cause errors on other cylinders (I found out the hard way). Also torque those puppies down good. Check ALL plugs are torqued down actually... they tend to back out sometimes (my 06...

    Five Star SCT TSX REVIEW

    So?? I'm still on my first tank with 87 Perf/Tow. Running great. Idles absolutely perfect.

    Cat delete

    I find that odd. I did a cat delete and nothing but good resulted. Better power, fuel economy, torque...Engine computer didn't mind it at all. I'd be willing to bet you have other problems. I do have a tune but the benefits from deleting/replacing the cats was easily felt beforehand. Really...

    Rough Idle

    Realize poster has solved re cleaning IAC. My 2cents on idle. VCT's are cheap and easy to replace on 1st and 2nd gens. Do replace them on higher mileage units. First place to go when you have decent miles and idle issues and the dreaded rumble strip or mild misfire/OD shifting issues.... Is...

    What oil/filter do you use?

    Once I switched from a 5W-20 to a 0W-30 the 5.4 finally sounded like it should. I personally think the resulting touch increase in oil pressure is enough to help out the starvation issues in the top end. And this oil is 'thin' enough to perform well in any climate, year-round. Shell's current...

    Plug change... 235K and (surprise!)

    Good plan getting OEM plugs and coils. A couple of mine came loose after a few months. Torqued em down and now great. Fuel filter is important too. My 06 also responded well to Gumout Regane cleaner. Have a tune on it now (once misfires were sorted) and at 298,000 KM runs best it ever had...

    Five Star SCT TSX REVIEW

    So I jumped on the Five Star sale of 249 for the older TSX tuner. I didn't want to spring for an expensive unit with display and only wanted the 87 and 91 tunes. I've had an SCT tuner for the Mustang for almost 20 years and am familiar with operation and a computer geek by trade so I wasn't...

    What kind of engine oil everyone uses?

    Canadian Tire Motomaster OEM Plus Euro. LX 0W-30. Truck LOVES it. Runs quiet, smooth. This is same as Shell Helix Ultra ECT C2/C3. Same as Pennzoil Platinum Plus Euro LX and same as Quaker State UD 0W-30. Arguably the very best oil Shell currently makes. Blended in Germany and Canada. Try...

    .40A PARASITIC DRAW THRU PDB 15 & PCFP 17

    I experienced same power draw issues. 06 EB. It was the rear wiper. Worked but was not fully fully returning to original position. Pop the glass on the rear hatch after you exit the vehicle. If you hear a click after opening, its your problem. My solution was to not use rear wiper anymore...

    Torque Converter Clutch / PCM Solenoid - what does what

    The article did not give me any indication on whether to replace the Torque converter PWM solenoid or the Torque converter clutch solenoid. Anyone?

    Torque Converter Clutch / PCM Solenoid - what does what

    As in most other cases, turning off OD eliminates the problem completely.

    Torque Converter Clutch / PCM Solenoid - what does what

    Sorry. PWM Solenoid. I have the 50-55mph shudder. I have ruled out Universal joint on my 06EB but it fixed some wonky vibrations. Tightening plugs fixed my (everyone thinks it's a normal Ford 'tick' sound especially in drivethroughs). TIGHTEN YOUR PLUGS PROPERLY BEFORE CHANGING COILS. Change...

    believe torque converter shudder

    Hey Moose. Ever get an answer if this fixed the 50-55mph shudder? I have ruled out Universal joint on my 06EB but fixed some wonky vibrations. Tightening plugs fixed my (everyone thinks it's a normal Ford 'tick' sound especially in drivethroughs). Removing/replacing catalytic converters...

    Driver door doesn't latch

    Dont lock the doors. Put lock deicer down door lock button hole inside and inside actual latch inside the door. Pull the outside handle a bunch of times and even work the actuator inside the latch a bit if it wont catch. Park so that the sun hits the drivers door and it wont happen. I greased...

    Get the plugs tightened if there is a tick. Top up the oil.

    Check the relevant fuses too.

    Heck of a deal

    Fuel pump pressure module attached on the chassis goes. If she still turns over its probably that. 50 dollar part

    Ford F150 & Expedition Front Hub and Bearing Replacement

    Creef14 very easy job. Didn't do it myself but little labour required as the entire driveshaft does not have to be removed. An hour labour probably? I'm sure some of the guys on here would be able to give you the entire replacement procedure. If she is up on a ramp you should be able to...

    2005 Expedition 5.4 Triton 3V misfires

    I had similar problems after a plug change. Couple bottles of fuel system cleaners straightened me right out. One was seafoam and the other was Regaine with gumout.

    vibration when accelerating from a stop

    Check your driveshaft U-Joints for play. Causes all kinds of funky stuff. Common problem in these. Cheap fix too.

    Rough idle5

    I'd do all the plugs and coils first. Then look at the other injectors. Then MAF / TB and check your vacuum lines. In that order.

    Ford F150 & Expedition Front Hub and Bearing Replacement

    Just so everyone is aware.... If your driveshaft u-joints are bad or going bad, you will get some mysterious hums similar to bearings that are worn out. I replaced two bearings before figuring out it was the ujoint. I have an 06 4WD and one of the driveshaft u-joints was shot. Rides like it...
