Type of car
Has anyone dealt with this kind of issue on the MK3 focus? What solutions worked for you?
I'm leaning to get the intake valves walnut blasted and see how that goes. Has anyone done this and noticed a significant change?
- 2014 Ford Focus S
- Manual - not plagued by the automatic transmission
- 82,000 KM
- Cold start, idle is pretty rough until the car warms up
- Once the car warms up, Idle is mildly rough. When you stop the car and the idle regulates you can feel small shudders in the steering wheel and peddles.
- I find when I give it a small amount of gas when parked can trigger the rough idle if the vehicle is not currently showing symptoms
- Adding additional load on engine can make symptoms more prevalent (Air Conditioning)
- Vehicle is not throwing any codes and not showing misfires.
- Changed spark plugs – no change
- Changed air filter – no change
- Cleaned Mass Airflow Sensor – no change
- Had ERG valve recall performed (recall 18V735000) – no change
- Checked for vacuum leaks – none found
- Replaced Throttle Body (mechanic advice) – no change
- Used crc gdi intake valve cleaner (Ford recommended the intake valved be cleaned as they may have excess carbon build up) ford did not have the machine to do it at their shop. I'm trying to get an appointment for a shop that that the professional equipment. I tried the over the counter stuff in the meantime – No change
- Ford said they adjusted the motor mount as well which also had no change.
- Combustion leak tested - OK
