Looking for some help. While driving my 1990 740 gle (104,000) the car stalled and the check engine light came on. I was able to restart it in a few minutes but it seemed to run a little rough. I finished the errand I was running and headed home with it running fine again except the check engine light was still lit. I pulled the codes at home but need some help interpreting them. While #2 was jumped I get a 2 3 2 and while #6 was jumped I had a 1 4 4. I reset the computers and after idling in the driveway no new codes were set. Will be using the car today to see if anything comes up. I know the 2 3 2 may have been a vacuum leak a while back that I never reset after repairing. But I'm new to the 1 4 4. No load signal means exactly what?

Also I have a Bosch ignition coil on the right strut tower and I'm not sure which systems are in the car (LH-Jetronic, EZK, REX...). I am the 2nd owner and the car was previously well maintained.

Any help will be greatly appreciated.
