86 305 code 33
 

I am new hear and tried to find the answere to my question.
I have an 86 iroc, bought it in 88. Started to have maf codes and took it to a dealer. Under warrenty they replaced the maf computer and chip.
Worked for awhile and then I parked it due to starting a family.
I got it out off and on and still had problem with the code 33.
Last year I decided to work on it. I replaced the maf senser which I didnt think it needed. I took it to a dealer and it sat there for 2 months. That was enough of that. I have found the bulitin that there was a problem with the original chips. I replaced it. Still have the code. Now I am looking the the power relay and the burn off relay. I also found the bulitin that the part numbers were wrong in the GM books. Where are the relays. I found one by the battery where is the other one.
I am sorry if this problem has been addressed before and I didnt find it.
Any help would be great.

I also wanted to add that when it is cold it runs great. I can burn the tires all day long.
When it heats up is when it acts up. This is why I was thinking it is a relay breaking down.

here is a photo for the relay locations. i would look into them and the wiring if everything else has been replaced and its still creating issues https://camaroforums.com/forum/attac...9&d=1280189017

Thank you so much!!!
What relay is right in front of the battery?
This is a great site. There is alot of information here.

that one im still trying to figure out. mine was replaced and rewired and some point, and i would like to know where it goes to as well

After 22 years I finally got it!!!
I bought a chiltons book and just started to check everything.
The first thing I checked was the throttle position senser. It was suposed to be between .45 and .6 volts when the key was on and not running.
It was at .65, set it at .53 and runs great!!! I also found the cut off relay was mounted on a rubber strap. I think way back then the dealer thought it was vibrating.
The relay in front of the battery is the cooling fan relay.

ah, well thanks. now that i know what that is i can remove it im glad you got it running well
