i have a 92 firebird with a 3.1 engine auto tranny

i was wondering how to pull codes off the computer.

and what kind of tranny i got.

i looked around on here i seen headers for 2.8 not 3.1 does anyone make them, and pulleys also.

 

pullys, aspracing.com, do not get the alt pully, just the crank.

codes, can be pulled with a paperclip and a haynes manual from local parts store.

tranny, auto=700r4, manual=wct5

the headers will fit a 3.1 if your not in a smog state.

 

so i have a 700R4->T5 tranny,

i have a repair manual, but i can find the thing to pull codes from,. can u tell me where is it at please, thanks chris

so u are talking about this pulley

88-95 2.8, 3.1, 3.4 25% Crank 900 RPM ASP541800
$64.95


do u need to get a smaller belt

 

Yes you will need a smaller belt, when you get your crank pulley it will give you a part number for the belt for your specific car year.

 

engine question

when my engine is cold, its got full power,

then my engine is hot. i lost power,

i change the cap, rotor, plugs and wires.

and my engine light is on, and im trying to figure out how to pull codes and see why the engine light is on, can someone help me chris thanks

 

you short out termainal a-b, and count your check engine light flashes. The repair manual tells how.

you have a 700r4, I missed that you said auto.

correct pully, and whatever belt they list, get one half an inch shorter, mine slipped.

engine runs in default mode when its not warmed up, as well as its generally sucking colder air. So it will feel more powerful then.

May have something wrong, but doubt full. Check all your engine sensors.. ECT, O2, TPS,

 

thanks so much, do u have a pic of termainal a-b

or where it is

 

the OBD terminal by the fuse box...

 

under the dash on the driver side right

 

yea, close enough. Prob something you could hit your knees on?

I belive a-b is the upper right two.
jump it with paper clip.
turn car to "radio on", or just the cick past.

then count the blinks.
Will start with blink, short pause, blink blink, long pause=code 12
will repeat that 3 times
then on to next code

it all should be in that repair manual.

 

sory if im bothering u, i just put 2 paper clips in ,

the paper clips are touching or not tounhing, last question

 

bend it into a u shape.

 

why does everyone say not to run the alt (ud) pulley? i'm running it and the crank pulley, i have stereo stuff, and i have no problems with it, at all.

 

it can cause low voltage.
the 90-92's have a higher amp alt I beleive, so those years are not as problematic using it.

Hell, I just went with a high output alt on my 92 and the car just flat out ran better... all the power I could ever need, nice bright lights and all. 140 amp solves everything.

 

ok. cause i never do have any problems with it.
