ok got the beast on diagnostics today, but the mechanic that did it wiped the codes before i had chance to write them down! doh! it came up with 3 main faults, HALL SENSOR ERROR ENGINE SPEED SENSOR ERROR LAMBDA CONTROL PROBLEM INTERMITTANT (something exceeded) he said the hall and engine speed sensors would be to do with the crank and cam sensors, is that right? and he's told me to get a new lambda sensor, should i? anyone ever seen these codes before / know where i should start? thanks, Katie
