"Money can't buy happiness -- but somehow it's more comforting to cry in a CORVETTE than in a Kia"
Thank you so much for your comments. Unfortunately I am in my final exams period and do not have the time to keep up with the car.
However I did order a cleaning spray for the contacts on the connectors and will try to pull the codes. But, as you say, I will order a o2 sensor and change it because the one that the car has seems old.
I also will search for slop in the carburetor and check if there is a vacuum problem.
Nevertheless I will also consider in replacing the ecm. Is it very difficult to do? I do not own a shop, only a craftman set and good will doing mechanics.
Thank you very very much.

ps: changing to a non computalized system seems like a great idea.

Hello Sarge and Joel, I finally finished my exams and got time to get my hands on the vette.
I changed the o2 sensor for a bosh one. The old one seemed to be very old. The results were as follow: car improved lightly, still feeling it a little "fat" but I feel as I have no fair judgment since it has been a while since I last drove it. But it definitely improved.
nevertheless, the check engine light is still on and I can not pull the codes. Cleaned the contacts with nail polisher and special contact aerosol.
I was thinking in reset the module to see if that clears the code and the light won't show no more. I guess that is be unplugging the battery, but for how long?
Other alternative I was considering is go ahead and change the ecm. When I bought the car, the alternator was overcharging the battery and gases really came out of it, maybe that produced some damage in the ecm since it is right next to the battery.
I could really use some advice as to which steps to take to identify the problem and solve it.
thank you so much for all the help.

Yeah, I will probably change the ecm and see if it fixes it and if not change the prom as well.
Now, I have seen some ecm and my best choice is a holley remanufactured one in 69 on ebay. I gues I will get the chip from summitR. What do you think?
Thank you very much.
I ve finally fixed the problem.
By replacing the ECM with an ebay listed holley remanufactured $69 ECM and using the same prong not only does my car ride excellent but also the light is gone for good.
Thank you once more to all.
Merry Christmas.
