Model141.5tp1297 air leakage fault code in front of throttle.

The throttle valve is not installed or matched well, but the meaning of this fault code is estimated to be that the throttle valve is not installed properly and there is air leakage! The throttle valve of 1.5T is not easy to disassemble and assemble in the direction of the firewall, especially in that intake pipe, which is not easy to install, the idle speed is unstable, the acceleration is weak, and it is easy to stall!
