i have a code 5 for knock sensor and a code 16 for egr. would eathe of thos 2 codes make my car run rich

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

its a 93 v6 with a klde motor. its got the klde vaf and ecm. and the k8 intake man. with klde injectors.

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.

there is no cat on the car. it has straight pipe. and i could not get the de im to work cuz i could not find all the vac. lines.

and the de intake is off the probe. so it looks like the neck is stright kinda so i dont know if it will fit if some one can tell me

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).

you can feel it bog down from getting to much fuel

and mazdags can u post a pic of the motor in your car with the probe stright neck intak on it cuz i didnt see one in your work log

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.

cool man thanks. ill be waiting to see thos pics of the motor in the car. lol and ill look up the de vacum dig.

pics posted!

ya i seen them. thanks. its looking good. my intake and valve covers painted im just waiting for the money to get the valcover gaskets. autozone here wants 85$ for 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!
