3vze code 12
 

ok ive searched code 12 and every thread talks about it but nobody that ive seen has ever came back and said, fixed it this is what it was or anything. im getting a code 12 on my 1994 v6. starts up runs rough seems like the computer kicks in and times itself then itll run ok but acts up sometimes, but allways for the first 10 15 secs untill the computer makes up its mind....thanks for reading and thanks to any replys

I doing this from my phone, so I don't have anything to reference...
IIRC... Code 12 is open or short in NE circuit, open or short in the STA circuit or the ECM.

My only advice to you is check all the wires. What has changed since before you got the code and now? If you replaced anything, go back and revisit what you did. Gotta troubleshoot.
