I love these two videos; I have a 1978 Town Car that has the exact same problems that you started out with. Now I know pretty much where to start as to how I can correct this issue. Thank you for being so thorough and explaining the process.

This is the bulb out feature. It does this on purpose. Welcome to 60s technology.

So I'm confused. What was the problem valve cover?

Flux capacitor.... Too funny

Anyone find a source for just the potentiometer and not the whole assembly?

I got the same exact truck

Great video, thanks for the detailed walkthrough. Used this for reference putting my Mazdaspeed6 engine back together

Ty.. just did this today.. the belt i replaced split in half and wrapped around the fan.. new belt is on but testing it it slowly comes forward on the upper pulley.. i turned it off before it messed up.. but with the ac engaging there was a high pitched squeel if you could call it that.. on the tensioner.. what is the exact symptom of a failing tensioner? Is it throwing or shredding belts?

Thanks for the great video just picked up a new to me 02 7.3 starts right up but definitely runs kinda rough going to check over my whole engine harness after I fix the preexisting issues 👍

Where are you located at? Got a 2008 6.4 with the exact same issue. It has left me stranded MULTIPLE times. No codes though. I've taken it to several shops. Everything from New Fuel Rails, pumps, etc. All guess work. Still have the issue and have spent more than 6k to remedy it. I'd like to get mine to you depending upon where you're located.

Ok so if it only blows out of defrost that means I have a bad pump or bad reservoir?

What’s up I’m having the same issue same exact code rpm is about 1k at idle scan tool reads around 700rpm truck runs great but if I put it in drive it has little to no power put it in 3,2,1 it drives fine Is there a follow up video did you fix the problem ?

Need this guy to look at my truck 😂

Thanks for this video. It was very good info regarding carburetor issues and cleanimg. Started first pull after I cleaned that little orifice with a tiny floss brush. Guess I need to be more diligent in running this thing every 90 days.

Dude, you are my hero !!! Had the same issue and was trying to find the problem for nearly two months! Thanks a lot for such detailed video!

Your POA valve sheet is wrong referencing 1977 - 1978 Lincoln, Mark IV and 1979 Lincoln, Mark IV. 1977 Began the Lincoln Mark V run, into 1979. 1980 Began the Lincoln Mark VI. Probably other misprints but I sighted in on those from your sheet.

So it was a bad injector? Sorry little confused

Great video...wish I would of watched this 2 weeks ago. Damn flex fuel option!! At least I have all new O2 sensors, MAP, Charcoal Canister, and fuel pump now in my Tahoe. LMAO....yes I do all of my own work but this could have saved many headaches for sure. Thank you! BTW my alcohol is at 59%.....Ughhhhhh

I have a 78 Lincoln Continental. Have you done any videos replacing the heater core? I just bought this car and the heater core has been bypassed.

One thing to keep in mind, because it got me, is that there are different sending units. You have to buy the right gallon sending unit. Some of these online retailers don't tell you what gallon tank the unit is for. I have an 18 gallon tank. I bought a sending unit that was supposed to be for my truck, I got it and it kept hitting the bottom of the gas tank when I tried to put it in. It was only about an 8th inch off. I was unbelievably confused until I figured out that they sold me a 19 gallon sending unit instead of an 18 gallon unit. There was only a small difference between the two, but it was a gigantic waste of time and money for me. So watch out for that.

You are a fine human being my friend! I totally could not figure out why there was no fuse in the #27 position labeled " trailer tow battery charge (if equipped)" I was thinking my $75k dollar F350 didn't come equipped with a trailer charge line!! WTF!! Your video was amazing and right to the exact point of the same issue. I've since re-labeled the manual on #65 fuse😊. Thank you so much my friend. Huge help!!

This helped explain a lot. I just have a question, where does the vacuum supply inlet at on the control panel? My 79 isnt getting vacuum to the actuators and i cant find a vacuum line for it.

I have a 97 PS that intermittently wont get over 2,000 rpm, I've replaced injectors & wiring harness, IDM, fuel pump, main computer, throttle pedal, glow plugs & harness, fuel pressure regulator, fuel bowl, fuel lines, fuel tank screens, cam position sensor, ICP and IPR sensors

Thank you so much for your video. Bought the same replacement component over 2 years ago for my Mark. Difference is it's front passengers side mounted. Haven't gotten to doing the repair yet. Needed to see what your video showed. Antenna is up and won't come down. I know now after I get the inner fender wall off how to get the antenna apart so it can be retracted and removed for repair. Glad I waited 2 years 😁

Great vid, very detailed and informative!

Hey thanks man great video, any idea how to get those panels off in the first place?

this was extremely helpful. Thanks for taking the time to upload this

Good video, I had the same issue on my 79 where the heat was stuck on no matter what, I removed the same valve and tested it with a vacuum pump and it didn’t seem to work, but it turns out it had an adjustment screw on it, I turned the adjuster in and the valve started to work, you can see which way you need to go by looking down the tube and seeing which way the lever pushes on the valve, depending on if yours is stuck on hot or cold, a couple turns in or out might get it to work again

I have an 85 ford E 350 econoline that has a 2 tank switch original.my problem is one tank doesn't register on the dash to see how much gas is in it, the other, does. How can I gat both tanks to show on the fuel guage? I run the non showing tanks first, and when it gets the odometer near what the miles are by miles per gallon, andhave to be ready to switches the tank runs out by paying attention, to switch at the right time. It would be nice to have both tanks registeron the Guage to make it easier. Any suggestions?

How thick are the spacers ?? Thanks

keep at it. you will be ok!!

Thank You So much I have 1 the same year model and my accelerator pedal is 1 - 2 inches from the floor after it got stolen. Yes loss power try to shift especially in 1 - 4 . I have no codes though. Hopefully it's just the stretched cable.

I have he same problem with the low of hi pressure and I have change the iPop twice....myself. I will be checking and change out the pressure regulator.

how did the valve body gasket look?

None of us are perfect. We all make mistakes. It’s how we recover from them that matters. You’re taking care of your customer so I’m hopeful that will be appreciated in the end and this doesn’t harm your business. We NEED honest mechanics and not dishonest ones so we can’t lose you brother! God bless~

You have to put STA BIL in the gas and run once a month with a load on it.

Man your Awesome

Not the same engine dude...

What is my gauge is past “F” and doing what you did didn’t make it move at all

This is a great video, very helpful, thanks a ton

Could this cause long cranking and no start? Mine runs great for random leangths of time then dies Usualy when coming to stop

HELP. Anyone reading comments please help. New ICP New IPR. I can hear air leaking under the oil rail but cannot find where it's leaking from. New Dummy plug and New Standpipe. I have taken every injector out and see nothing wrong with the ORings.??? Where else can it be leaking at?????

Excellent video! All around with the diagram, wiring locations, procedures, explanations, troubleshooting. Everything. Just a good solid very helpful informative video 👍. I have a 2013 2500 and chasing this same problem only without a volt meter. Might be time to get one.

I have a 77 Town Car. Your videos are money brother!!! Thank you.

What did you hook it up to in the body control?You show a wire but it doesn't show where you hooked it

3:22 I went on the computer and still couldn't see. Looks like you unscrewed it. Thanks for this video, it's going to be really helpful

Great video 👍 been looking for one for ages so i can replace bearings in my 1987 town car,do you have any play in bearings with your wheel on and hands on wheel 6 and 12 o clock moving it up and down?also is there a specified torque for doing it up? thanks

Just pulled my ipr and did my leak down test. I’ve got air leaking on both sides like this one in the video. Mine is a 2003 f350 do the 03’s have dummy plugs? Sorry for the dumb question ha!

I am very familiar with Panther cars (Crown Vic, Grand Marquis, Town car) and I can say with confidence that the passenger floor pan most likely rusted out from pooled water coming from a deteriorated cowl air inlet seal. When they dry up (and they always due) it's best to remove the air inlet cowl and reseal it with Permatex gasket maker. Once that's done you'll never have to worry about water leaking from that cowl seal ever again.
