Electronic throttle control
I have recently had an issue with the ETC light flashing on as soon as the gas pedal is pushed enough to put the car in boost. I have searched this problem and havent found my exact situation or answer.
Here's the things I've noted.
Only happens once the car is in boost, drives perfect without boosting.
Only code is a p0420, assuming because my car has no cat.
The RPM's don't fall when the problem occurs, but the boost gauge will drop significantly as the car starts to lose power.
Where should I go from here? I have read of issues with the throttle body but unsure what exactly to look for. I called a local car repair company and they asked that I clean the throttle body, however I haven't seen that being an issue in searching so not sure if there's an benefit. thanks for any input.
