Fuses would be my first guess. I would say check the computer connectors but not easy to get to on c5.
My 98 ta would give me problems with trying to scan it. key was on position but said no power...

Anyone?????? I got $50 to anybody that can help me with my idle problem.

update.
took ecu off found blue connector has water damage. swapped out computers an now both side read lean but idle is better.
here is a log.

I also noticed that my low oil light is on but its not low.
i'm thinking I might have a burnt wires on passenger side which is why its running rich on that side.
funny thing is I have no codes...

What do you mean crossed o2? sorry i'm little lost.

ok got brand new 42# injectors now o2 passenger side reading rich driver side lean.
fuel pressure at 58psi.
maybe intake leak?
no headers leak.
