did the koeo and koer tests today, been noticing it was running a little strange sometimes.

i got codes 11 and 33 in the koeo test.
i know 11 is the system ok code, but what about the 33?

I also got code 44 in the koer test, the book says its the termactor air system fault. I have no idea what that is. any help would be great.

thanks
Dan

Was the car warm... up to operating temp? If not, your computer will throw incorrect codes.

I don't have my code book handy, otherwise i'd look it up for you.

code 33 in continuous memory, I have EGR valve opening not detected. That is from the Probst book.

code 44 is the thermactor air crap, thats emission control stuff, I have those codes, doesnt matter to me.

I wish I had a scanner, but I dont, get the Probst book and go to town fixing it. Or else you will pay someone else to fix your car. Well worth the $30 investment. One day I will get a scanner and give you guys the page you need.

If you have deleted some or all of your smog pump stuff, then you will have to live with that code 44. Mine throws that code and drives fine. If you have all of you emissions control stuff in the car still, and you have inspections, you might want to look into fixing it. I have never worked on that stuff, I have always removed it.
