suspect tune up (wires ,plugs ,filters )
check fuel pressure
and if u have check engine light on need to scan for codes
let me know
the check engine light is flashing to alert you to the fact that the engine has a missfire in the ignition system, don't continue to drive this with the condition or u can overheat and damage the catalytic converter.
SOURCE: engine revs remain high or increase when braking
Have you tried checking your throttle positioning sensor. Possible vacuum leak or check for carbon build up in the throttle body not letting the throttle valve shut all the way.
SOURCE: 2009 Hyundai Sonata-clicking noise at brake pedal,brakes applied
This is not a rich mans car so its normal. Your hearing the solinod that lets you take the car out of park after the brake is depressed so the car can't be put in gear unless the brake is on. If the noise bothers you the soliniod can be found and wrapped in insulation like a rich mans car them you can ride on feeling like a rich man too. ( the Beatles sang that a long time ago) and its still true today.
Testimonial: "Thanks. Dealer hasn't been helpful. I'll see how far I can go before I run out of patiencs."
