1994 GMC Sonoma Question: possible throttle body issues, high revs and pushing forward when braking

 

Question

I have a 94 sonoma 4x4 that when driving, when trying to stop, the engine revs high and it feels like I am giving it gas when I am not. When parked, the engine revs around 2k rpm now instead of around 1k like it was before. Recent problem. Has not thrown a code yet...

    An engine vacuum leak or a sticking idle air control valve would be the most likely cause for a high idle condition on your 1994 GMC Sonoma
