koeo is as expect:
31-81-82-85-83(maybe it was 84, cant remember...all egr and emissions based stuff)

cars runs fine except first start up until its all the way warm it feels like it has a 5000lbs anchor dragging behind the car. once its to temp the car drive and operates just fine, but its not fast like it was. i ran koer and i get code 12 and nothign else. can i get some help?

dunno what is code 12?? I'm lazy

FivePointOhh · 09-14-2009, 11:18 PM

12 - RPM unable to reach upper test limit

I think 12 is in ref to the part of the koer test that requires you snap the throttle??

(O) = Key On Engine Off test
(R) = Key On Engine Running test
(M) = Memory code

31
31 EVP - (O, R, M) EVP signal is/was out of range

80 SERIES CODES GENERALLY ARE CIRCUIT PROBLEMS THAT COULD BE WIRING, RELAY OR SOLENOID RELATED.
ONLY ONE OF THE CIRCUITS LISTED UNDER THE CODE IS USED ON EACH VEHICLE. THE FAULT IS IN WHICHEVER SOLENOID OR CIRCUIT IS PRESENT ON THE VEHICLE

81
81 Boost control solenoid
AIRD solenoid
3.0L SHO - Inlet Air Solenoid

82
82 2.3L TC - Fan Control wire shorted to ground
AIRB solenoid
3.8L SC - Super Charger Bypass Solenoid

85
85 2.3L T/C Automatic - 3/4-4/3 Shift solenoid
CANP solenoid (ALL 1989)
(M) 1.9L MFI - System has corrected rich condition

83
83 High Electro Drive Fan circuit fault
EGR Control solenoid
3.0L SHO - Low Speed Fuel Pump Relay circuit

12 Idle Speed Control motor or Air Bypass not controlling idle properly (generally idle too low)

Judging from what I see here, you've deleted EGR and AIR pump systems, and you need a new IAC.

not worried about the 80's codes. i know my emmissions are gone. im worried about code 12 since it wont finish the test i dont know what my koer codes are

you can get a IAC for $60 from 50 resto....

I clean mine out everytime i clean the MAF

FivePointOhh · 09-15-2009, 10:26 AM
