Idle engine torque is ~800rpm after warming up without aircon.
(Too low, engine may stop; Too high, higher petrol consumption)3 ways to adjust (OFF YOUR ENGINE FIRST!)1) From Engine
- This is the first solution and it is the easiest. Only go to further solutions if the result can't be achieve.
- First, touch the 1mm play string (2nd picture). If there are many rooms for it, means your car is underpower.
- Adjust the 2 screws to tighten it up.
- What if too tight? you'll see your engine idle rpm going up.[attachmentid=2435917]
[attachmentid=2435918]
[attachmentid=2435919]
2) From Pedals
- If adjusting from engine doesn't work, go the the top of the pedals at the driver seat.
- Add whatever rubber or anything you can think off (which is safe) to tighten it up here.[attachmentid=2435920]
3) From Floor
- Last resolve and most troublesome for me
- Open up the floor at the driver seat and cut/modify the board.[attachmentid=2435921]
Don't speed, drive safe![attachmentid=2435922]
