shabby

New here, and really frustrated,I recently purchased a 88 Iroc 305, it first off was sending a code 33 so I was told to change the Maf burnoff and maf sensor relay. I still ended up with the same code, then I changed out the emc, signal then changed to a 36. Inow have changed the auxilliary oil pressure switch and I am still getting the same code. The car really runs rough at 1000 rpm. hardly wants to run. Looking for some help, any ideas would be greatly appreciated.

looks like a wiring issue code 33 is a high voltage

i know nothing about codes but could a vacume leak be making it throw a code?

archemedes

Thanks for the replies, I just finished checking all my wiring and my connections, evrything seems to be good. I don't have a vacuum sensor, it has a maf sensor I installed a new. Is there anyway I can bypass this code 36? Any ideas? Thanks again.

I started with a code 33 I changed out my maf sensor, the code then went to a code 36, I was told to check my ecm connectors and my maf sensor relay connector , how do I check them to know if they are good? Also is there a way of testing the ecm to see if its working? Thanks
