Idle problems !
Hi All, I am having continuing idle problems on my W Reg 159 2.0TS. It idles between 2000-900-2000rpm most times, although on the odd occasion it sits at 900 constantly. The car starts from cold and will sit at 2000rpm and once warms up it starts with the hunting. One point i have noticed is that in traffic if you keep your foot on the brake whilst its hunting the foot pedel drops maybe upto a third of its complete travel, I wonder if there is a fault in a pipe to servo or something?? Have tried the following.... Cleaned out MAF, cleaned out throttle housing (this did help initialy) checked for obvious air leaks, tried reseting ecu( disc battery) and the throttle reset procedure. I have had a friend plug in his snap on fault code reader but all clear. Any ideas ?! Any thoughts greatfully recieved
