Hi everyone! I just purchased this -88 Trans Am GTA from Calirfornia. Actually one week ago. It got almost three months to get in Finland.
It's my first F-body!! And I love it! Black and 350TPi engine.

But yeah here's the question. SES-light is on and I checked error codes and if I got them correctly it was 36 and 44. Both codes comes three times right??
So what I do??



When I put in on "P" the idle running is sometimes almost 2000rpm. Is it something to do with these error codes?
The throttle cable stays little "open" put just a small touch and it goes back and idle running is ok then...

Sorry my english, I'm trying

At the age of your car, a new O2 sensor and MAF burn off relay are probably long overdue but check for wiring faults 1st
Rockauto ( rockauto.com) are cheapest for service parts and will post overseas cheaply using USPS if you ask


Throttle cable may be sticking (disconnect cable from TB and check for free movement )
but most likely the throttle body is worn and the butterflies are sticking partly open when you let off the pedal which is why when you tap the pedal they close properly and the revs drop.

Only real fix is a rebuilt one

( is cheaper to pay the extra core cost than have to post old one back to USA )

or a better cond used TB from 3rd Gen for sale dept

'Throttle cable may be sticking (disconnect cable from TB and check for free movement )

Thank you very much guys!!! Great links also!! I'll try to fix that with those advices!!

Yeah, I also though that the main problem is that it takes more gasoline than normal BUT in Finland gasoline costs about $9 per gallon... (1,65€/litre) so..... So when I fill up my tank it costs about $124 or more..

I dont actually know about US but I think it cheaper there

And I meant that it goes back to normal if I touch that butterfly(?)-thing.. That thing that is under-the-hood-end-of-throttle-cable. I dont know all the english words

 

The throttle body ;equivalent of a carb on non injection engines
(commonly called just the "TB" on here)

 

Okay! Now I know that! Thnx! I have TPI and u said non-injection engines??

 

Hi there all, I own an 83 trans am with 350 carburated engine, the check engine is lighted but can´t scan the computer, I tried connecting a jump wire but stil nothing, can any one help me?

 

Will get more attention if you start a new thread titled "can't read codes " or similar instead of re-opening an old one

You are jumpering the correct wires?
