I just bought a 2000 RX300. The car would start but wouldn't run if I took my foot off of the gas. I followed step by step directions from a old forum on a this web site. I tried to take off the screws to the right trottle but with any forc ethey started to strip and i can't get vice grips in their to remove the screw. I have talked to two mechanics and they want to replace the whole trottle assembly.
What should I do??
