Is there some tutorial I can watch or in-depth instructions to make the plates fully open or remove them (K7 600)? I want to try this before replacing the throttle body/STVA and verify its not a fueling issue.The line has nothing to do with the code. The line indicated the primary TPS adjustment at idle. C29 is the secondary throttle position sensor. You should check the connections and test the sensor. Did you remove the STVA from the throttle body?
Ok removed the main connector and opened the plates by hand. Didn't seem to fix my bogging problem even though the dealer said my issue had to be due to bad STVA. Tried seafoam injector cleaner/octane booster and that definitely alleviated the issue although not fix completely. Should I have disconnected the STVA position sensor too?Unplug your STVA main connector and turn the secondaries wide open by hand. You'll have an error code, but no power loss.
