1999 Volkswagen Jetta Q&A
1999 Volkswagen Jetta Question: Check engine light is on and idle is fighting the brakes. What is the cause?
What do you mean when you say the idle is fighting the brakes, and was the check engine light on before the brake problem occurred? - BBMW
Is there any noticable 'hissing' inside vehicle when brake pedal depressed? Maybe brake booster is bad causing a vacuum leak- that could cause high idle and difficulty braking. - ziptie12
