Im in need of a tbs sensor for my 89 turbo as its idling around 500rpm and is getting worse getting annoying at trafic lights as it wants to stall all the time ive done tontrols which is on all the time is this normalhe diagnostic check and 51 comes up could any one tell me where I could get one in the uk if possible as I need one pretty soon also Ive noticed a green light on the auto button on the aircon controls is this supposed to stay on all the time? thanks

If the idle is too low just turn the screw up. Thats easy to fix. code 52 is knock sensor signal. That means your knock sensor is bad or disconnected.

having a dead knock sensor or a fault on that circuit may also cause the bad or low idle....since the knock sensor is part of the ignition timing circuit or function lets say.... fix that problem first ,that may fix the rest.
