hi ,
code 34 is the map sensor manifold absolute pressure, code 34 indicates volatge is low in the component , it is located on the left side of the firewall , this should take care of your problem if you did replace the maf and not the map sensor

i dont think i have a map since i am using a maf sensor instead. I looked for the map and i didnt find it. Is it on the passender side of the car or the driver side or in the middle?

Hey ChevyII, i replaced the relays and it seems to work fine now. I have looked everyone for the MAP sensor but i cant find it. are you sure a 1986 corvette will have a MAP sensor. This corvette is the ZR1.

By the way, my passenger window will no go down all the way. I have taken out the panel but i cant seem to take the window motor out.

thanks for all the help

yes it does have a map , i even went back to the books to make sure (gm books) as far as the window , the motor should be bolted to the regulator which is bolted to the door and also the window , just look closely roll the window up a bit until you can see the bottom throgh the door skin and you will see how the window is disenagaged from the regulator ,and the map may be on the left side manifold it is there somewhere , but the software says on the firewall should have a vac line coming from it to the intake

thanks
jim
