It wasn't smoking, but it definitely needed a top-up between oil changes before she sold it. She tried her best to destroy that sweet little car between 1979 and 1985.

It's good to hear that at least I likely won't be having any trouble out of this engine. It's in the shop right now getting a brand new A/C, and we're struggling to find the correct steering rack for it. Cardone apparently has a slew of mis-boxed 22203F racks, box labeled 22203T (the one I need). We're on the 3rd one, and it's wrong too.

Once I finally get it back (2 weeks now), she's getting all new weatherstripping, and shocks & struts. Brakes come after that. I'll probably take it somewhere and have the carb gone through.
I tried my hand at carb work with a few of my past motorcycles, and I just don't have a talent for it.

Wish me luck!




Forgot to post a reply.. That is one MINT 82 mustang notchback! Wow.. I remember the post now, those are replica TRX wheels, since now you can use NORMAL tires instead of only one tire (TRX from Michelin).

Would it be possible to post interior shots? Love to see what the interior looks like.. On my 82 hatchback I had the red/burgundy colored interior.

Is there any steering rack part available from Ford? That platform was used up until 93.

So I wish you well, keep us posted!

Is the O2 sensor downstream of the air pump? If it is, don't bypass the air pump or the air/fuel mixture will be wrong. Of course, who knows if the O2 sensor is still accurate anyway?

Typically they pump it in halfway through the catalytic converter which is way downstream of the 02 sensor (if this car even has one!)

O2 sensors became a requirement back in 1981, so this car does have one.

The reason I mention ensuring the air pump works is because the Olds 307 located the O2 sensor downstream of the air pump. By doing this, the engine could run a richer than normal AFR. That is why Olds experts recommend not removing the air pump from the 307. I figured that the Ford MIGHT fall into that category.

They were used on most 1981 cars, but weren't required, if the manufacturer could pass 1981 emission requirements without. My 1981 did not have one. By '83 or '84, the same model did have it.

Thanks for the tip, I actually have one waiting to be installed. I planned on replacing it even though it doesn't seem to need it at this time. Keeping my eye on the oil level.

Had to install a replica Dash cap and there is a small tear in the lateral bolster on the driver seat otherwise the interior is in really good condition.

Sorry to say. But hey at least I could tell ya it was done before with my 200 I-6.. One other thing, you just can't kill that engine! The body of my 82 fox body rusted out before that engine ever gave up!

Maybe others have a better way, but I never found one back then.


Hey, do you think I'd have that problem if I just the EGR and install a block-off? Just looking for options.

hey thanks for the interior pictures! I have to ask, has your Amp meter ever moved its needle? I remember that thing hardly ever moved. Yup that interior was very similar to mine, except I had a 4-spoke steering wheel with cruise control buttons on it, and the seats had a cloth insert. But other than that, thanks for bring back the memories!

I think you were trying to say REMOVE the EGR and install a block off plate.
Blocking off the EGR is exactly what that mechanic did back then and it carbonized up. So you would be right back to what I was talking about earlier with all the problems. At first you'll think that everything is perfect, but over time it will get worse and worse.
 
Thanks for letting me know! I think I'll just leave it be. :)

I've got some custom seat covers coming in matching red. That vinyl is SLICK, and cold. Being in that car brings back a lot of memories for me too. My sister used to cruise me around in a nearly identical car when I was a kid.

I miss it, as it's still in the shop (2.5 weeks now) dealing with the steering rack issue. Cardone, and the rest of the rebuilders have stopped producing the rack that's in my car, and it's been superseded by something that they're having a hard time getting the lines connected to. These old cars are fun, but can be a pain too.

I've got a pile of seals and weatherstripping that I'm itching to install. I'm kinda glad she's sitting inside a shop during all this rain. :)

yeah I know it's tempting to try and eek out more power from that engine, etc.. but the best thing is just getting it running the best it can and it is what it is. Cardone.. the joke about that is yup youre car IS done.. have you tried Ford? I mean anything up to 93 might work. sorry to hear you're going through such a tough time! I also replaced my steering rack back in the day, but that's when the parts from Ford were still available and I knew a guy on the "inside" at Ford's parts depot. He's passed away otherwise I'd call him for ya!

Ahh so you're going to go with a cloth seat cover! Good job! Yeah that vinyl can be cold, but try sitting on it when it's 100 degrees outside! AAGGGHHH!!! lol.

Yup did the seals before too, wow this thing is sounding exactly like the path I took back then!

And thanks for the pictures of what your sister's mustang looked like. Yup that I would say is maybe a 79 or 80? The door open handle is down low and there's no center console/arm rest either. but cool memories.

keep us posted on how it goes!
 
It was a 79. I wish they had left the door handle and lock knob the way they were. I thought it was so cool how they seemed to engineer it to be impossible to break into with a coat hanger. (Or that's the reason I came up with for why they did it that way). Integrated into the arm rest...what a cool place for a lock knob! Then someone complained and it all changed to be more 'normal'.

My 1982 3.3L had no O2 sensor. It had a carb and there was no way to electronically control(no ECU) the air/ fuel mix. I did have to do some "cheating" to get it to pass emission tests back then.
A note regarding the air pump, don't disconnect the belt unless you are sure you will never use it again. It will surely seize up in short manner if it is not rotating.

FINALLY got it back last night. The had my steering rack rebuilt, as nobody can seem to provide a new or rebuilt one that actually works with this car. A/C worked great on the drive home, steering is no longer dripping on my driveway. Then, this morning, the universe (or the car) sent a message. I walked out at 6:30 to hear the car hissing at me. UGH! The metal-to-rubber fitting on the newly-rebuilt suction hose is bad. What's so odd is that it chose that time of morning to fail, to make sure I heard it. It had all night to sit there and fail, but it chose ~6:30 this morning, so I would KNOW it failed. LOL

Put it in the garage and drove the newer car to work. The weather man says I'm likely to need a defogger later today, so.....

Back to the shop she goes. 3.5 weeks and counting. Old cars are fun, right? Right???
