have a 94 Z28 A4, car runs great, when cold!! In traffic or hot day the car will begin to rev on its own, yesterday, while hot, it sat in "Park" and i watched the idle jump from 900 to 1500, then 900 to 1700, then down to 1200 back up to 1600-1700, etc. While stopped at a light i almost hit the car in front of me, i was lightly holding my foot on the brake then BAM, lurched forward about 2-3 feet!!

WTF is goin on ??

I have been to 3 different mechanics and i took it to a chevy dealership and of course they said they could not duplicate the problem, bullshit!

Hopefully someone here can help me out. TIA, Craig

PS. gas filter changed, air filter changed, injectors cleaned!!
