Deciphering pulled codes February 12, 2012, 04:39:21 PM KOEO2 1 2 4 2 1 2 4 then a long pause followed by 1 1 1 1Is that 2 codes - 21 and 24 and then whats the 1 1 1 1? Searched for a code list and couldn't find one. Hopefully it relates to my hesitation / bucking problem I posted about here http://www.foxtbirdcougarforums.com/showthread.php?32977-New-member-with-a-few-pics/page3 Quote Selected
Deciphering pulled codes Reply #1 – February 12, 2012, 05:24:46 PM How to run codes, including links to what they meanhttp://oldfuelinjection.com/?p=1311 means system pass. It says all codes twice so you don't miss them.21 means ect (engine coolant temp sensor) out of self test range. If your car was not up to operating it can throw this, and if it was warm, the sensor might be bad. This could cause your car to run rich, and possible buck.23 tps. (Throttle position sensor) out of self test range. This needs to be replaced.I would replace the tps right away, clear codes/pull battery for 20 mins to see it if goes away and sets the idle right. The ect thing, could be because you have not had your car warmed, so I. Would check that again after clearing codes and see if it shows up again.If there is a vacuum leak, it can also cause a high/bucking idle. On my own cars, theidle was set too high and would actually make the car try to either cut fuel to lower the idle, or cut timing. Basically, after replacing the tps, you need to reset your idle in a way the computer can still control it.Unplug iac (the sensor on the front of the intak, between the throttle body and egr spacer) start your car, turn your idle screw down until the engine is barely running, then plug the iac back in. Clear codes, should idle fine after. Any questions, come right back. Quote Selected

Deciphering pulled codes Reply #4 – February 12, 2012, 05:35:39 PM Dang it, I remembered 24, not 23 sorry. Ect and act were out of self test range. I'm guessing your engine wasn't warmed up. Do a key on, engine running test. Thanks. Quote Selected

Deciphering pulled codes Reply #8 – February 21, 2012, 05:06:06 PM is this for a 2.3T by any chance? if so, you may have the same issue i just conquered.. then again. it's possible with a 3.8 and 5.0.. i've been rustling with this stupid car for a bit now, trying to get it right.. while my ECT was shot, it didn't really fix the problem.. today, i changed my TFI on the distributor (took a total of about 4-5 hours running, off and on to finally show a code).. i had a brand new TFI in the console that came with the car, so i replaced it.. it took away the miss and bucking idle.. i then went through the 'setting idle' process to get her where she needs to be, and she now runs like a dream.. i still can't move it, as i'm waiting on wheel bearings and brake pads, but i'm willing to bet my issues are gone now Quote Selected
Deciphering pulled codes Reply #9 – March 09, 2012, 03:25:19 PM Replaced the ignition module and hesitation is 90% gone I think whats left is just a matter of needing plugs and wires. Thanks for the help and I am putting it up forsale I loaned a family member money to buy the car and as much as I like it I need that money back. Check the classifieds if you are interested.
