Does any body know where to start looking for the reason for no code 11 when a koeo test is made? i am using a code reader i do get fault codes 95,81 and 82 but no code 11.bad ecu?
87 mustang maf conversion.
 
Nope. Code 11 means test passed.


Keep in mind there are three test that are run, two are with engine off, and 1 with engine running. So it's possible to get three code 11s

Code 95 means you did not run a wire from eec to fuel pump relay under seat when maf conversion was done. Doesn't affect how car runs.

Code 81 and 82 are tab/tad solenoids....did you remove them?
 
Hello,

I'm new to the site. I'm having surge problems with my 90 mustang gt. when I dump codes i get codes 67 and 22. I've replace maf, iab, and o2 sensors. Can anyone suggest other items to investigate? thanks
 
Please open your own post and I will post the 5.0 Mustang specific code definitions and fixes for your code 22 & 67. Piggybacking on someone else's post is bad manners, and people tend to ignore you since they may think the problem has already been solved.
