On a dry day she works perfect
On a wet day with heavy showers, if she is left to idle (take foot off accelerator) she goes into limp home mode after few seconds and puts on engine management light on dash. When u turn her off, let her sit for 5 an turn her on, she works perfect.
If u coming do a junction an take your foot of pedal to brake, she does it. However if u use your left foot to brake an keep your right on the throttle to keep her open, she doesnt do it. When driving she is normal through all speed ranges. It only happens when idling.
Mechanic has changed throttle potentiometer, air flow meter, took the wires out an taped them up, there no breaks in them, with good continuity through out. He now talking that it could be the brain, which couldnt be cos it only happens in rain. Brain is "Dry as Snuff" inside in his words.
Any1 any ideas- it gets annoying when she does it 3 times in 20 mins!
