![]() so I pulled my codes today and I don't know what to do about some of them
KOEO: 67, neutral drive switch fault, switch open circuit/ AC on during self test I don't have AC so it must be the neutral drive switch Continuous: 63, throttle position circuit fault I replaced the TPS not too long ago and never cleared the memory KOER: 41, injectors out of balance 91, EGO sensor problem due to fuel pressure or injectors out of balance 33, canister or EGR valve control system not operating properly because of the injector codes I did a balance test and cyl #7 came up what can I do about the injectors? can I clean them or can I do something else, I don't really want to replace them Thanks

![]() no one knows anything about these codes?
I guess PKRWUD hasn't been on the board lately

![]() I dont know about your other codes but the one about the AC switch circuit being open could be because you have the wiring for the AC. I had a code similiar to this on a dodgey dodge. The car had no ac but it had the wiring. Hope this helps.

![]() Conman,
First, was your car experiencing any sort of misfire problem before you performed the KOER? If so, disconnect the #7 injector plug to see if the misfire gets worse. If everything is running fine, I would suggest an inline fuel service that will allow the injectors to clean from the inside out. An in-tank fuel additive would probably work as well, but it would take a little time before you noticed the difference. BG enterprises offers a product called "44K" it is comprised mainly of liquid ether or something like that which clears the deposits out one layer at a time. The A/C code is nothing to worry about, it is merely what would be referred to as a "ghost code." The EGR code however is something that needs looking into. Given the information you provided I would suggest checking the vacuum control lines between the EGR valve and its vacuum control solenoid. They should be easily tracable. I hope that this helps. 95GTNut |

![]() You need to reset the ECM, and run KOEO again, except this time depress the clutch pedal during the entire test.
Post the codes. Take care, ~Chris

![]() a couple more tidbits of information, the reason I pulled the codes is because the car was running strange the other night, didn't have much power and idled low. The stock guage was reading normal but I think it was hot, I was doing a lot of stop and go and putting around cause I was doing some deliveries. Once it cooled down it ran fine and has ran fine ever since.
I reset the ecm and pulled the KOEO codes and got 67 again I got 11 for the continuous codes One question PKRWUD, how did you know I didn't press the clutch down? I looked around the EGR valve and didn't see anything out of the ordinary

![]() Did you depress the clutch pedal the second time you ran the codes?
Also, is all of your smog equipment still installed? Take care, ~Chris

![]() yes I did the second time
I have an offroad H with the little pipe blocked off From the air pump it is just pumping into open air, I havn't got around getting an idler pulley and removing it, other than that I'm pretty sure everything else is intact

![]() Run KOER again, and if code 33 comes up again, double check the vacuum lines for the EGR. If they're good, use a hand vacuum pump, and slowly apply 10" of vacuum at idle to the EGR. What happens?
As far as the injectors go, you can try swapping #7 with a different cylinder, and then repeat the power balance test, and see if the bad cylinder follows the injector, or if it stays at #7. If it moves, the injector should be replaced. If it stays at #7, you need to perform a leakdown test on that cylinder. Take care, ~Chris
