Answers :

Code 27 : Injector circuit isn't switching when it's told to (TBI )
\015\012\015\012OR (MPI) injector circuit #1 not switching ri ght
OR (turbo) injector circuit #2 not switching right
OR (all 1990-) injector output driver not responding

hi as you can see this code has to do with your fuel injectors,firs thing that you had to make sure is that if your computer harnes is not loose, to do this just unplug the computer harnes and plug it back, then if this does not correct the problem you have to do the same plug and unplug thing to every injector and if this does not correct the problem then you may had a bad injectors and you have to replace them, the cheapest way to do this is to go to a junk yard and buy a used fuel injector rail so you don\302\264t have to replace injector by injector just replace the entire rail wich its more easy to do, hope this helps.
