Is there a way to reduce idling speed from 1900 to 800 during morning.
I do understand that high idling speed is no good for the engine which will shorten the bearings life.
When idling and I press the brakes the brake pedal eventually sinks to the bottom

Check out the coolant temp sensor and have the IAC system checked out, I feel that a faulty IAC may be the problem.

1. RPM meter at dashboard has a red light and keep on blinking.

2. Lock the car with remote anf after 5 minutes or so the alarm comes on.

3 The red light on the RPM meter keeps on blinking

Brake Sinking.

With engine running at idling. Step on the brake and the brake pedal slowly sinks to the bottom.
There is a limiter half way through. So the brake pedal goes down as far as the limiter allows.

Please let know how to overcome the problems above.

Thank You

Paul

The brake pedal sinking will be a faulty master cylinder, get this done first.
