i just ran a koeo and koer test along with a cylinder balance self test. the results from the koeo i think was 3,3,1,3,3. the results from the koer was 1,5,8. and the cylinder balance flashed 9 times. can anyone translate this? thanks help

33 in KOEO, is an EGR opening not detected. Do you run the EGR? If so it could be vacuum line off, or bad EVR solenoid.

Looks like you need to run the KOER test again. Those numbers don't match up.

9 on cylinder balance test = pass.

yeah on the cylinder test it flashed 9 times, paused then flashed 9 times again. ill run the koer again tomorrow and see wut it says. as far as the koeo goes i could've possibly misread it, it was a little confusing. and what do you mean by run the egr? would this cause it to be a little sluggish ?

the egr is located on the spacer between the throttle body and the intake.

liljoe07

No, that EGR code won't cause it to be sluggish. But if you need the EGR functional, you need to track down why. That's what I mean by run the EGR, meaning functional.

ok im not really worried about the egr. should the car be warmed up when i run the codes again?

Fox fellows, the SN has three digit codes....Code 158 Is MAF above max voltage. Not a code 331 so to assume is code 313 air not bypassed during koer test. Cylinder balance is single digit code 9=pass. Run test again and post results using the three digit code format. Bubba

ok will post new results soon. should the engine be warm when running the test? and what exactly does it mean by maf above max voltage ? thanks.

i ran all tests again and took a video of it so maybe someone could decipher it for me. youtube keeps giving me errors when i try to upload unfortunatly i did the cylinder balance test 3 times and got a 9 everytime. ill keep trying to put the video up.

The maf signal goes up to 5 volts. I used to max mine out when I put a supercharger on it. Then I went with another meter. Is it cutting out at wide open throttle? What all is done to your car?
