Ok I've read a bit on the K-jetronic but I don't know the system and how it really work in depth. A new symptom arose today when I back off the throttle in low rpm like in city driving the car would stall or many times ALMOST stalls. Goes down to around 500rpm and stall or barely pick it up and back to 1000. On full electronic cars we have the base idle setting and the AIC does the rest of the job. A problem like this one would probably a lazy IAC. Is it similar on K-jet? Is there a Idle control on each bank? Could the base idle be set too low. But it never did that before today since I own it. Time for me to learn the K-jet system in depth.
No, no IAC on Bosch CIS injection (as used on TR). What engine family do you have? US (F113A040) or late euro (F113B) or something else?
I have the F113A040. I was thinking at my NEW problem yesterday night and could it be the 02sensors that I have interchanged connections left to right giving the wrong reading the system is trying to adjust with the mixture on the wrong bank making it too rich or too lean.
Disconnect them completely and see what it does. It should run perfectly without them. If it's OK you can sort them out later. Black is for right bank and white is for left.

Thanks, I didn't look at the wiring itself but I should have thought about it earlier. I will check for that.
