New cats, new O2 sensor, repaired front exhaust leaks and I still get the 1223 code from time to time (typically as it warms up...)
Tell us what is the exact problem and model of 164 you have please. You say in post 14 you have 164L but in an earlier post you say you have a 94LS 24v if that is true what I said about relays is almost the same but slightly different. Still same 4 relays but different code numbers for cooling fan ones - I99 low speed and I100 high speed and there isn't an ignition coil on bracket on 24v models.Hi Steve, appreciate your precision. It is the two relays on the coil bracket...the right is the fuel pump and , I guess the left one if the fan relay which has 85 and 87 bridged. Why......I dont know.
I will take the wire out and see if the fan starts or, I will let the car run untill the fan kicks in and then pull the relay and the wire out and put the relay back in and see what happens.
How does that sound?
Could be O2 sensor getting lazy or something else is tricking it and it can't adjust problem past it's +/- monitoring limits.To continue my discussion with my Q and the 1223 code. This is really bizarre behavior. after checking all the hoses, finding nothing amiss and cleaning the connections with DeOxit and making sure the connections were solid, I cleared the codes and went for a drive. I got a 1/2 mile this time before the red light kicked in. I could make it go out by taking my foot off the accellerator. The light would go out. I drove a 6 mile round trip loop. The light would come on, foot off the accelerator it would go out. A couple tenths of a mile the procedure would continue several times, until the light came on and stayed on about 4 miles into the test drive. The car ran fine the entire time. I am wondering if it has something to do with the O2 sensor?
