Hey everyone, after a long search for a 3rd gen Camaro I fell upon a deal on a 92 Firebird that I just couldn't pass up. The deal was 2 Firebirds for $1500.00. Two whole cars. One is a Formula 305 TBI, the other was a v6 nothing special parts car with no title. I love this car! Ive been working on it literally since I got her home, her name is Dorthy...Dorthy meet the guys...girls......ok. I found her on craigslist and walked with $1500.00 cash across south Pueblo to meet a very sad seller that wanted to say his last goodbye before I took her home. Of course I gave him the time he needed with her.
The driver door didn’t shut right at first and opened even worse, I though it was bad censored cause it’s a T top, I just jumped over it cause Dorthy’s a race car.
And the saga begins.
Anyway I've done a full tune up of course, completely rebuilt throttle body except for the fuel pressure regulator. I did one and screwed it up so had to put the old one back on it. Ran out of time. I wished I could have spent more time but Its the only set of wheels I have at the time and it was after 10:00 (Im having a serious timing crisis with my 97 Tahoe crawler/daily driver but thats another thread in itself) and it is my wifes daily driver to work. (thats what originally it was bought for)
116,000 original miles.
After the usual shakedown tune and lube I’ve run into a few issues.
The first one is the fan that was bypassed by the original owner to a toggle switch. Ugly mess but solid and road worthy for now.
Second issue, Windshield wiper switch/wiring
This one is a complicated one. Ive spent a day going through the wiring to find that I had some shorts in my fusebox, several unknown wires that look like a stereo gone bad, and charred areas in the fuse box from some electrical burning.
For now I had to bypass the wipers with another toggle switch and take out the clutch/gear in the wiper motor. If anyone knows what that is called please tell me because it took me a few hours to figure out why my wipers were only traveling an inch back and forth. I’m telling you I al lost my cool big time on these. My friend and I spent a whole day on figuring the wiring out to where the problem was, then ran out of time because he had church to go to. He’s an older guy, cool old retired machinist though. But what it takes is taking the white gear on the right of the inside of the wiper box out so the main gear is forced to engage every time.
My plan with this is to splice a new fuse box and various other wiring parts from the v6 car to the v8. Solder it, make it nice.
Any guidance or insight on these wiring issues would be appreciated. Ive had several GM TBI’s but this is my first F body.
Another issue is there is a thumping noise when I accelerate under the passenger side floor. After some research I think this is a transmission mount or a torque arm. I’ll find out tomorrow if the snow isn’t too bad.
How do I find out if I have a POSI without popping the cover? Or is there even a way? I’ve looked up the casting number but haven’t really come up with anything.
Im taking the cat off, to my understanding one of the O2 spacers will take care of this unlike the chips I had to wire in for my vortec?
I’m going to be ordering some chip programming hardware here soon, I’m brand new at the tuning thing so any advice on that would be appreciated too. What software does everyone recommend?
Thanks for reading ladies and gents! Hope to hear from you soon! Im going to get more info on the tranny and block number tomorrow as well so ill update then!
