91 Factory S/M ???

[CEThomas]

Anyone have a PDF of the factory S/M for a 91? Need to find out about the code 27 "Fuel injector control circuit" that I have on the MJ.

I found my good ol' fashioned paper copy and it says that 27 means the "Injector output driver does not respond properly to the control signal". Or whatever that means. :hmm: If you can get it scanned with a DRBII tool, apparently it'll show which injector it is.

Thanks.
