Traction control, heartbeat sign, engine check and service light on



  182
The 182 has decided it wants to be in limp mode now for 3 days. I've plugged my rs tuner in for diagnostics after the above 4 lights came on. It said map sensor, throttle control limits acquired (not at fault) and throttle pedal position track 2 input as present faults and a abs communication memory fault ( but the cv boot leaked grease everywhere and the sensor is covered in grease so I know this as I normally have abs and traction control lights on. I bought a new map sensor but the fault will not go away. And the throttle ones go away when I disconnect the plug on the throttle butterfly and reconnect (it also buzzes when the fault is there)
I haven't got a clue what to do now as I've tried 2 new map sensors and checked the wiring quickly that goes from the sensors to the ecu as much as I could without ripping it out and the faults won't clear. Any ideas because limp mode is doing my head in and there is no obvious reason for this fault to be here!!
cheers
