well we could use some more details.
like do you have a 4 banger or a big 6.
is ur motor swapped. or no?
and what year.

haha from what you told me.
you have something either seriously wrong with your motor.
or an extemely easy fix.
well your egr is the only thing that could make ur car run rich.
from those 2 codes anyways.
but it wouldnt even be noticable.
give us more info and we will be glad to help you

Maybe it's running rich because of using the DE injectors (more fuel) and the K8 IM (less air than if you used a DE IM).

Just a thought. Also, how rich are you running? Check your cat.

It fits, just check my worklog to see how...

As far as running rich, does it smell rich or is it blowing black smoke. Running not cat at all is going to make it smell rich (no filtration).

If there's codes that's making the ECU unhappy, it'll go into a Safe mode to protect the motor. One of the ways is to run rich to minimise pinging/detonation. I could see the KS code cause this, the EGR would be an emmissions thing

Oops, lol, sorry. I guess I didn't post them up yet. I will soon though. Basically, you just have to be careful of the brake master cylinder when putting it in. It does clear it, but just barely. Also, you can find several DE vacuum diagrams if you were going to be routing them.

Try ebay, theyre all just rubber gaskets and theyre not that bad to replace so I would check there. I picked up a set for my mine for way less than that!
