My advice to anyone with an SVX is to "Clean the throttle body!" what a difference, no surging, great idle,it actually seems to shift cleaner. I did not have the high Idle problem either. It actually appears to have dropped the idle a couple of hundred RPMs. The biggest difference is the low RPM range under load. much smoother. Took all of an hour and a half. There was an actual ridge of gunk behind the butterfly, all gone now. All I need is a fanbelt for the TR-8... it'll be 80 degrees here Tuesday
