Mein Auto: 1993 BMW 325i
Boging down

My 1993 325i has started to bog down when I turn on the A/C. Sometimes it will run fine and other times bog. I have noticed it has been turning over slow when starting. I had the charging system and battery checked out and was told everything is fine. Do you think a bad connection in the battery cable would case this? I had the same problem happen last night without the A/C on.
Thanks you your help.

Bogging sounds like the idle speed control is not responding to 'idle up'. Remove it and clean with carby cleaner. Check it for electrical problems. Slow starter - try inspecting every battery cable, joint and earth and remake any joint that is even slightly suspect. Dont forget engine to chassis earth.
