Hi guys,
I need help.
I just put a 97 B18B motor & ecu into a 97 civic cx.
i used the stock civic harness,
did the iacv fix &
wired in the different plugs correctly (alternator, crank fluctuation sensor ect.).
The motor runs strong but,
i'm getting code 91 which is tank pressure.
I'm lost & have no idea what to do.
I've done my research &
never heard about any other changes that need to be done to the wiring other than what i mentioned earlier.

Does anyone have any ideas?

Thanks,
JAY.

 

Yup. WHen I did my mini-me on my 97, it gave me code 91. I still have it to this day and just live with it. It's because ex's came with some sensor that the dx's didn't have or something to that effect. That's just what I've read.
