    flashing CEL, tow or limp home?

    My 98 XLT ruptured a heater hose and washed #3 and #4 spark plugs real nice and clean. I noticed immediately when it began to misfire. Two miles up the road it set P0303 as a pending code, five miles later the check engine light came on and flashed in short bursts. I drove it ten more miles...

    4.6 Windsor thermostat housing will not seal

    This is actually my wife's F-150 but it's a very similar engine to the one in my Expedition. I replaced the thermostat due to it throwing P0125, indicating the stat stuck open. I got a stat and o ring from O'Reilly and installed them. It leaked like no other, so, absolutely fed up with the crap...

    Murray/O Reilly compressors just junk?

    Yes on both but I can't tell you exactly how much PAG oil I put it. I can tell you it was quite a bit. I usually assume there is between 0 and 3 ounces of oil in the system and I add enough to fill it up. Residential ACs don't care if you overfill the crankcase a bit. That might explain the leak...

    Murray/O Reilly compressors just junk?

    I have put two Murray compressors on my 98 Expedition last summer. The first was rebuilt and bad straight out if the box. It refused to develop high pressure or any kind of suction; in residential AC terms this is called "inefficient compressor". I changed it last June, this time springing for a...

    Acid damage to compressor?

    The one it had when I got it had a leak at the shaft seal. Eventually the Napa one started leaking at the same place. The Murray one I took off struggled a bit developing pressure. There is no acid in the system. I used a QuickCheck 2000 acid test on the truck and on the recovery bottle. Both...

    Acid damage to compressor?

    This is the third compressor that's gone bad in my '98 Expedition. The one that was on it was bad when I got it. I took it to a mechanic to have a new one installed; they put a NAPA Cold Power and it lasted a little over two years. I replaced it myself with a rebuilt Murray unit that lasted...

    A/C System Recharge. How much oil to add?

    Oh, if you are putting in that much 134a, buy a 30 pound jug of it and forget paying $25 a pound for it at O' Reilly. That's highway robbery. You can also fill it with certain gas dusters. You'd have to change the pressure switch for one out if an R12 system. I did that on an antique F-150 and...

    A/C System Recharge. How much oil to add?

    The best way to check for leaks is a hydrostatic test with dry nitrogen. It takes a few minutes and leaks can be pinpointed with soap and water. That said, I believe you've got a satisfactory leak test. My own Expedition also calls for 14 ounces of PAG 46. I always pull a vacuum and suck the...

    System Too Lean (Bank 1 & 2)

    I had that same thing happen after a 90 mph run up I 45 ftpm Houston to Dallas. I broke the PCV tube getting the elbow off. The replacement parts cost $7. For a while I had PO401 also but it just vanished. I think some of the carbon buildup got sucked into the engine. It runs good. Had to...

    Ignition key cylinder disassembly

    A while back I picked several key cylinders from various Ford trucks at the local Pull A Part. Most of them were in the LOCK position, but one wasn't. I pulled the tumblers from the one that wasn't locked and swapped it into my 98 Expedition. The one it had was wearing out to the point it...

    ! Wanting to swap engine with a diesel moter

    Would the front suspension even hold the diesel engine up? One good speed bump and it's bye bye ball joints...

    System Too Lean (Bank 1 & 2)

    This^^^. They may have ripped or disconnected a vacuum line when they were replacing the alternator. For those codes, thoroughly check your vacuum lines first. Forget the O2 sensors--those are just money makers for the parts store. They do need replaced once in a while, but not for PO171 and...

    Healthy engine vacuum and DTC question

    So how about the vacuum reading on a healthy engine? 18? 21? More?

    Healthy engine vacuum and DTC question

    Most of that stuff is now under lifetime warranty. The Check Engine light went out but the code is still set. I will watch it to see if the light comes back on and if it does, I'll clean the ports here at home. I did some research on the exhaust tube. If that's clogged I can blow the carbon back...

    Healthy engine vacuum and DTC question

    TL;dr What's the vacuum supposed to be on a healthy 4.6 engine. Are there any serious DTC codes the truck might throw? The old truck threw me a P0401 yesterday which I traced back to either a faulty DFPE (sp) sensor or clogged ports. I replaced the sensor last year, which cleared that code...
