Hello.
I have an is 200 running on lpg, have had the engine rebuild since the idle was so bad, like if it was running on 3 cylinders.
When the engine was opened , in cylinder numerb 2 there was a damaged exhaust valve, .
HAve replaced em all , new , also new piston rings, and cylinder hear overhauled.
The engine runs smooth on petrol and lpg, but there is a problem with the throttle body, it kinda gets a fault when I give full throttle.
TRC light come blinking on as well as the engine light. Have tp turn the engine off restar it and be careful not to push the accelerator pedal too much.
Anyway problem is either on lpg or petrol. It is sad that after all the money I spent I still have a faulty car.
Have swapped the trottle body, and problem is the same...
Codes are:
P1128 :Throttle control, engine locking
P0120:circuit switch A sensor pedal / butterfly, malfunction
P0121:Switch circuit A sensor is pedal / butterfly position, field / performance problem accelerator pedal position sensor
any Ideas now?
Thanks
