Hi all,
Have noticed that if i turn my air con on while for example i am stopped at the traffic lights, engine will drop to 200rpm and kick itself back up to around 800 then fall back down to 200 and do the same over and over.
Car usually idles spot on at 1000 and when i turn the air con off, it returns to normal.
It is an intermittent problem and does not happen every time, but quite frequent. i actually took a video with my phone today so you can actually see it happen (dont have the cable on me - i will post it later).
Any ideas on what could be causing this? have only noticed it happenning since i got a power FC installed and the car tuned if that helps?
Cheers in advance for your always brilliant ideas / support / advice!
