Throttle Body Cleaning

When the Throttle Body is dirty, idle instability, hard starting and sudden shutdown at idle occurs.
To clean the throttle body it is necessary to disassemble it, for this you have to disconnect the hoses (some coolant is lost), disconnect the throttle cable and remove the fastening bolts.
Use a Carburetor and Throttle Body Cleaner product, clean generously with the cleaner: air inlet, air outlet to the intake manifold and IAC valve passage.
It is not recommended to remove the IAC valve when it is electronic because the RPM is decalibrated at idle, when this happens it is necessary to calibrate the RPM with a scanner.
