My 1990 Formula
Thanks in advance for a warm welcome, I've been lurking here a while and figured it was time to participate. I was born and raised a Pontiac lover and was actually a Pontiac salesman until 2010.. Still am a GMC/Buick/Cadillac salesman, just no longer offering our beloved Pontiac.. I'm a homebody with a wife, two dogs, three adult kids, some of whom have children too 


On to the cars:
The wife's pride and joy (my Yukon in the background):

Our most recent acquisition:

Needs some work but has lower miles (73k) and isn't too rough. 305 Automatic with T-Tops.. Headlights need some repair and major adjustment:

I'll be using this thread to compile my list of needed repairs, though I'm not NEAR as detailed or efficient as some of you on here. Meantime feel free to toss out any criticisms or suggestions.
Paint needs some TLC, seals need replaced, interior could use a refreshment AND the hatch is out of adjustment pretty bad. First things first though, the headlights. The motors work but it appears as though some of the components are broken so I'll need to take that all apart... And probably pucker up, eh?
Glad to be here!

Looks good, 1990 is a rare year for these cars. Only 4,000 or so Formulas built that year.

Re: My 1990 Formula
That's one of the main reasons I traded for it! I was hoping to doll it up and have a decent investment, though so far I'm probably into it for more than its value, considering the repairs and reconditioning it needs. I'll probably go through and get some more extensive photos tonight or this weekend...

Re: My 1990 Formula
Probably bit off more than I can chew, once again. Oh well, I'll learn a few things, I'm sure..
Under the hood:


Missing the under hood heat shield, eh? And that underside of that scoop, is that factory? Bolted on like a high school student did it....
Oh, then there's this:

Eeeeewwwww..... Hopefully a coolant flush will cure that one. Damned thing needs an oil change too!
The wheels:

Pitted pretty bad, wonder if they could be sanded down and re-cleared?

Re: My 1990 Formula
The paint issues are there, though I have yet to fully examine them... But I can already tell that the repainting wasn't that "professional" and the paint issues go from bad:

To worse:

Same spot with or without flash, there's some sanding marks and such but hopefully they're in the clear and I can operate...
The interior is actually in very good shape!


The headliner area has seen better days though:

Re: My 1990 Formula

BTW, speaking of our year being rare due to short production, I read there were a little over 4800 Formulas produced for 1990. However a couple of years ago I read somewhere that of the 4800+ produced, only 52 of them came with the 350 v-8. 5.7 engine. My old computer crashed where I had saved this info. and have been unable to find it on the good ole interweb since then. Can anyone point me in a direction to find this info again, or verify what I read?

Re: My 1990 Formula
Had a bulb out in the rear so it was a good time to mess with this, well, fuggin mess:

Seems a previous owner has stained the plastic with something.. The crap liked to have never come off.. Hit it with a microfiber pad and some Ultimate Compound:

Fun, fun... You can still see a hint of the stain in certain light.
Dunno if you saw the missing patch of black paint on the inside of the panel:

I plastidipped that, it disappeared! Awesome sauce....
Got all the tail lights back in a realized that now I'll have to buff both taillights too. I knew better! :sigh:

Re: My 1990 Formula
those headlight housing always seem to break on those firebirds. 2 birds I owned over the years had them broken also. I searched ebay for replacements and found some,

Re: My 1990 Formula
Yeah, sounds like I'm going to have to formulate another plan as well, epoxy just isn't making a strong enough bond on that thin of a spot... Damn, these headlights is gettin' 'spensive!!

Re: My 1990 Formula
Well the epoxy fix on the headlamp bucket didn't work... Luckily one of you fine members has contacted me and has one, so now we just wait for the parts to come in and get it all re-assembled! Meanwhile I've decided to go ahead and take the passenger door apart and find out what's wrong with the window/motor/regulator, etc.. When I roll the window down it gets about halfway then falls over.. When I roll it back up it get to the top and makes a horrid racket. I'm sure it'll be evident when I get in there.

The sound the window makes when you attempt to roll it up followed by the sound the window makes when you roll it down. It goes about 3 inches and stops.
Help?

Re: My 1990 Formula
Need a new window regulator. The teeth that the window motor runs on have striped out. Kinda like the gear you pulled out of your headlight motor.

Thanks for the reply! It was my suspicion that there were some teeth broken off of a gear somewhere.. So is there a way I can be positive of whether or not it's the regulator or the motor that needs to be replaced, aside from simply drilling the rivots out? Is it possible to take that whole setup out and spin that gear around where the stripped teeth are no being used (similar to that headlight gear you reference)?

Anyway.. Should have the other components by Monday, looking forward to putting it all back together and moving on to the other parts that need repair.

Thanks, I did see the option for a better gear like the anodized one you linked but I have found through my research that the gears rarely go... even on your link it states:
"NOTE: Gear failures appear to be rare on 87-1992 models"
AND I had one gear with zero damage, so I think I'll be good... Thanks again for the link though, can't have too many options.

Re: My 1990 Formula
None of my hoods ever had anything different than what you got, except an 83 T/A I had with the functional hood scoop stuff.
I usually take out the plug and let out some hot air with it. I've never had a problem with water or anything like that getting through there.
