I have a strange problem with my 735i 1988 while decelerating
The car jerks!
This is simple to reproduce just put in 1st set switch to “M” accelerate up to 40km and now I remove my foot from the accelerator now the car starts to decelerate fine!
The fuel flow meter pegged at “0” and the car start to decelerate fine
But then I get to a speed where the car stops to decelerate around 30km the fuel flow jumps from 0 to 1 and the RMP’s jump a bit to, this last about one second “jerky”
on off like this until the car slows down to 10-15 kmh and the RPM at 1100 until I stop and then after 5 sec the RPM drops to 650-700 but as soon as the car reaches 10 kmh the rpm jump to 1100
I hope someone out there can help me with this problem
background
the problem started after bleeding my brakes, I know that the two don’t have anything to do with each other
I must have disconnected something while working on my brakes
But I can’t seem to find what I did L

I first connected my vacume gauge using a tee to the small hose that leads from the intake to the lager hose from the valve cover rubber boot that leads the MAF to throttle see link” http://www.bmwe34.net/E34main/Trouble/Engine_diagnose.htm “ on this point I got on 5in.Hg
Could this mean that my PVC valve is not working?
I then connected my vacume gauge to a tee to the fuel presser regulator that I believe is connected to the intake and I only get 15in.Hg is that right?
I have looked for vacume leaks and I have sprayed all my vacume hoses with starter spry and noted no change in RPM’s
Other problems my735i seem to hesitate from idle
Left seat heater dose not work ( It’s –12c here in Sweden now)
A/C dose not work (not needed for now at least)
Thanks
Love this forum!

i>just got back from a test drive and I did not have this problem when the car was cold!
