    2003 XLT 5.4 misfire after weeklong rest

    I didnt attend to a misfire properly. Cost me almost $3K in catalytic converters. If emissions is important, take that into consideration.

    04 Expy underdash clicking

    It is the the shifter lock. brake pedal is super sensitive. Its a metal latch and its metal to metal. the slightest touch or vibration will send signal to latch and unlatch repeatedly even without toughing the pedal. replacing the switch attached to the brake pedal arm. probably looks like...

    03 Expy 4.6l Oil Leak

    I recently changed my oil filter adapter plate gasket. Not too bad, but you dump all your coolant. Part is only 15 bucks. It was a pretty decent leak. So time it with a coolant flush. Good time to inspect the bottom hoses as well.

    04 Expy underdash clicking

    It could be causing the noise but the noise is in the steering column. Just seems too loud and its quite annoying. I replaced the cruise control switch (sw5957) that releases the cruise control via brake yesterday while under there.

    04 Expy underdash clicking

    So I did a little more digging. The clicking is in the steering column and it is related to the brake pedal. I have a mess under there. (another thread perhaps). If i slightly touch the brake pedal and apply the slightest pressure I get the clicking. I noticed it in the steering column...

    2003 XLT 5.4 misfire after weeklong rest

    Sometimes it takes a while for a code to appear. about 50 miles. In the mean time the ECM will adjust air and fuel to try and compensate for the lean/rich condition until it gives up and throws a code.

    Number 4 cylinder - spark plug

    I just climb on the engine. I have removed the hood as well with a bit of help. plenty of light and I can reach everything by hand. I have done full plugs and coils about 3 times.

    04 Expy underdash clicking

    manual AC. I have had that before. this sounds like a relay and its kind of erratic and almost at the cluster or steering column.

    I have random intermittent clicking under the dash. I only notice in in park while engine on right after start up or after parking. any ideas or experiences with it? Only thing I know that isnt working is Cruise control. but never dove into it to see the issue. I can do the diagnostic if...

    No Heat at idle

    after warm... manually operate the heater valve and see if the hose temps change. could be a signal issue or the valve itself

    No Heat at idle

    is the heater valve vacuum operated? I know you said the HVAC system is auto, but if the valve is vacuum operated you may have a vac issue. Another thing could be the blend door motor.

    Sea foam? Anyone had any luck?

    I did add about 8 ounces on mine about a week before an oil change and did the intake spray before the throttle plate. There are some good before and after videos on the spray and oil additive. I also had a code that required a new EGR and DPFE. Unsure what part made the difference, but my...

    Any good After market catalytic converters ?

    Most companies will not ship to CA due to our CARB laws... even though they say carb compliant. I had them shipped to a friend and shipped to me. But I went with the straight and 45* and was able to drop the exhaust and weld them in. In order to be 100% legit, you need to drop about $4k on...

    Ac compressor squealing

    I would replace the compressor drier and expansion valve. You got your money worth on that compressor as they usually don't survive past 60k miles. To replaces the clutch, that compressor has to be removed anyways.
