Ix35 After cleaning the throttle,

1. Check the data stream handle with a diagnostic instrument. Insufficient acceleration is probably related to this fault.

2. See if there is any air leakage. Whether the pipe connection is correct and whether the glue is aging.

3. The car has traveled, depending on whether there are traces of soaking water in all the connectors of the engine computer and wiring harness. It has never encountered a similar situation before rust, and there are some strange fault codes in the computer soaking water. But it is rare. See how you soak.
