Another 2.0l fault code ..grrrrrrr

Post by bluepain » Mon Sep 13, 2021 3:34 pm

Had two fault codes come up the other day,both stating overfueling on tickover..
It was running a little lumpy when on tickover.
And stalled once when I came off the throttle to a halt..
Seems to run fine apart from the obvious stated faults..
These are the codes.

Well I had to resort to Google just out of interest.
The only issue I can find that shows up on both of those codes is a leaky injector?

Always happy to help if I can.

Too rich on both banks 1 & 2. Disconnect the MAF and see if it runs better.

Check for vacuum air leaks split or holed rubber pipes, high fuel trims and bad idle usually the symptoms

Will a cracked rubber seal on the fuel filler cap give a air leak great enough to give a vacuum leak.
I currently cant find any cracks on my hoses.

my best action may be a smoke test to find it.
