Lefeng 1.4 cleaned the throttle and idle motor, and replaced the timing set and the water pump. Replace the aluminum alloy cylinder head with four steel wires and four spark plugs?

p57。 This fault code means that the algebraic engine control is higher than expected. The possible reason is that there is too much carbon deposit at the throttle position. Or behind the throttle. There is a phenomenon of air leakage. The computer will detect that the idle speed is higher than an expected idle speed value. It will light the fault light. What you can check is whether the throttle is thoroughly cleaned during the cleaning process? Fuck. Is it possible that this has carbon deposits? Stuck the idle motor in the position with large opening. Then, second, do you want to see if the sealing ring at the back is installed when we install the throttle? Is there any air leakage?
