Ok I have a 305 ).. It's the electronically controlled carbed 305.. All stock (1986 Trans Am)...

Back story: The original owner was having trouble with it passing emissions. He took it somewhere to have them work on it. Well they "tweaked" it.. and it passed. Well I was having trouble with it running smoothing.. gas cutting out, idling high blah blah. Had 2 different shops look at it. It's pretty jacked up. Whoever played with it originally didn't know dick about carbs (lol neither do I... that's why I'm posting).

Situation:
Carb is having issues... So my question is what I should do. My mechanic (they're good and do alot with fbody's).. suggests that I get rid of the electronically controlled carb or whatever and just go with a regular carb... pretty much get rid of the computer crap. Regular carb & distributor and whatever else...

Is this the smart way to go? They say it's going to be more work trying to get the original tuned right etc.

I trust the shop.. but I just wanna hear from you guys. I know everyone's done all kind of swaps so this is minor.

What should I do? I'm open to suggestions (however I plan on keeping the 305... original 60,000 miles.. so no complete motor swaps).

 

Is it a tbi or a carb theres a difference.

 

shiiiiit. It's carbed. 5.0 4-Barrel

 

A shop's probably not going to want to invest the time and effort into making your stock system run correctly. They probably no longer have the tools, know-how or the manuals for that 20+ year old system AND don't want you coming back complaining cause some other 20+ year old sensor fails. If you want to keep the stock setup you can save a lot of money, keep decent fuel mileage AND performance BUT you'll probably have to learn to do it yourself. There's a lot of help here for that if you decide to.

If you just want to pay someone to band aid it quickly, do the swap. Expect to lose some mileage over an ECM controlled system and potentially some performance depending what carb you put on. Don't forget to also install a method for locking the torque converter once the ECM is no longer controlling things.

 

Thanks... Geez. I still don't know.

Are there replacement carbs for the one I have? The carb is messed up.. apparently there's something broken on it and its super rigged. They did what they could as is.. it runs a tad better but still not 100%.

 

Don't you need special tools to work on a CCC-Qjet

 

Nothing all that special is required to work on them.

Most any parts store will have or can get a rebuilt computer carb. Also available on the internet.

 

im looking into getting a remanned stock Q-jet still too when i can afford it. i found some on ebay (with good reviews, and lots of them of course) that will rebuild, or build the one you need for around 350.00 some with no shipping, or core refund. its expensive but from what I've found anywhere else its pretty cheap. Franklin auto told me they could get me a rebuilt one...but it would cost near 500-600$
