Not to be an a$$ but this post is pretty hard to understand. There are lots of knowlegable folks here who like to help, but they have to be able to understand your question.

Your car runs poorly? Did it begin running poorly suddenly, or did it run poorly before you got it?

Are all the wires in the engine compartment attached to something?

Do you have any "check engine" codes? What are they?

The first things most here will tell you to do, especially if you just got the car is give it a full tune up (plugs, wires, cap, rotor, fluids, check timing, replace any rotten or missing vacuum hoses). Cover the basics, then begin troubleshooting. Don't assume the carburetor is the problem.

 

looks good to me just don't post on it because i ain't doing it again cant i no i am hard to understander i live out lot of little words like "to was ,a ,i ,you" but thats ok peace

 

I can't understand what you're asking, you didn't use any punctuation..?

The more (understandable) info you give, the more useful info you'll get back.
I'd love to help you out, and I know a thing or two about the Q-jet, but I can't make heads or tails out of what you said...?

 

ummmmmmm.
ok ill have a go, Is youre choke opening at all?
The large plate over the front of the carbie, is it down flat or open so you can see inside the top of the 2 front holes?
If it is closed or almost closed it will be killing ALL performance and fuel econamy.

 

ok. I was on the phone when i first made that. I have a 1985 camaro berlinetta 305 . i don't ever use QJ but this time i am. to keep stock. the car runs fine at haft pressed fine but go an more. The RPM will drop and it will not want to get speed like it should.??????????

 

The car runs fine to half pressed (half throttle?) but go any more and the RPM's drop and the car doesn't want to pick up speed like it should?

Throttle position sensor?

Problem on the secondary side?

Do you have both the correct computer controlled carb and distributor installed?

 

ever thing is hooked up and i dont think the Throttle position sensor is bad. i have had those go bad and it is nothing like that. i am sure it is in the carb.

 

Is it still doing it after you completed the above?

Don't assume the carburetor is the problem until you've identified the carburetor as the problem. I read that somewhere.

 

yes done full tune up replaced ever hose even vacuum ones aw so change tran. filter. still got the problem like i did be for. no power when u push the Throttle past haft . push it past haft RPM drop and junt does not go any faster .

 

Some easy to check possibilities:

Clogged fuel filter-replace this
Choke stuck closed-make sure it's sitting straight up when the engine is warm
Choke pull off bad-remove vac hose, push it in, finger over hose nipple, stays in?
Secondary Air Valves stuck-tap with your fingers, it should move freely
Timing off/no advance-verify advance with a timing light

 

check for a bent fuel line from the carb.these QJ use a lot of gas.pull the altenator and check line that runs by the water pump thats were mine was bent at.

 

i did have a bent line but i put a new line in when i first got it

 

What carbie were you using before the Q-Jet?
What is youre timing set at?
Are all youre plug leads on the right plugs? (Not as hard as you think to mix up if you replaced all the leads at once).
Have you got an in-tank pump or block mounted pump?
Did the car have these problems when you got it?

 

i did not change the carb and the car was not running when i got it because of a cracked frame witch i fixed and i just used the timeing light on my car at it is timed at 10

 

cracked frame?

 

yea i got it off of a guy for like really cheap because the part of the frame behind the powering steering gear box was cracked .in about 4 cracks around witch will make the gear box flexed on the frame and u will have little to no steering. i work at a body shop so i just took it there and welded it . also redid a brake line that was leaking. an i have been driveing it fine. aww but the carb problim. it is worth fixing because the inside is meant and it is loaded ever thing power even cruise, ttops it is the berlinetta with the digital dash and the pods witch not many of those are left or where made.

 

other than what I have already asked i duno what it could be, I have never seen nor worked on a a CC Carbie (I had never seen a Q-Jet before i got my T.A).

 

think i will get a new carb. maybe some one had it apart or messed with the setting on it or it could just be old pretty sure a new carb. will fix it .

 

Don't count on a new carb fixing it. There could be several things external to the carb that could be causing your problem. Before spending ~$300 on another carb I'd recommend rebuilding the one you've got, adjusting everything properly and checking the operation of all of your sensors. Rebuild kits run ~$20. With some carb cleaner and a few tools you could get where a replacement carb would put you for under $50 (and maybe figure out the problem in the process). See a semi-recent thread started by Nate86 on rebuilding the q-jet.

 

you said ur timing set at 10.my 85 berlinetta says that timing should be at 0.reset ur timing and see what happens.i thinck the timing way off and the motors running retarded.i got the same car and mine runs great at 0 if you want advance it between 2-4 unless she starts bopping and detonating.

 

Make sure the flat 4 wire plug at the distributor is disconnected when checking the timing also.

 

yea i did check my timing right i made sure of it and i had a about the same problem with my 1978 olds delts 88 350 and i went out and bot a carb. i mean the different was like night and day ran like a dream after that so i think i will get a new 1 and about rebuilding 1 i dont think i could do that to many things to F up

 

good news i rebuilt my carb an the jets where just clogged so thaanx for the help ever 1
