Help me figure out my "Euro" problem. (Page 1/1) Wonders NOV 12, 07:35 PM Haha, no this isn't everyone complaining about european cars. This is however, a help thread for me and my family's 1991 Chevrolet Lumina Euro. The car has been acting like garbage since we got it last year, and here go a couple of the issues I remember. Stalling, dying when slowing down, and most recently, erratic idle and failure to start. We have changed the Coolant Temperature Sender, because that darn light was bugging us and it was fixed. As well as the IAC valve thing that we thought would fix our problems but didn't. Also the three front spark plugs. Me and my family have no idea what it could possibly be. if you do, or have a guess, please reply. One more thing to add, the ECM doesn't store the code after the car dies, etc. It always comes up 12, which is no distributor reference pulse. Raydar NOV 25, 10:32 AM Does it do it all the time? Just to troubleshoot, I would disconnect the TCC clutch connector. It should be a four pin, sort of square connector on the front side of the transaxle. Faces the radiator/core support. If the TCC clutch sticks, it will cause the car to stall when you stop. Similar to driving a manual trans car, and stopping without pushing in the clutch. You may have other stuff going on too, but this is free, and easy. Only takes a couple of minutes. If nothing changes, it's easy to plug back in.

Recently, my family has gotten code 23 and 44, if I have not already said that. They contradict eachother, because 23 deals with that little sensor that sits inside the air box, and 44 sits in the exhaust. However, once the car moves to open loop? it runs like total garbage and dies. lack f power, pushing the gas does nothing, etc etc black smoke. Wonders DEC 12, 08:32 AM Final update on this thread, the injectors of all things caused the problem. The guy who repaired the car also welded the o2 sensor hole shut, for whatever reason. IATS is just there, not broken, but still shows a code.
