Last week I posted a question about stalling at stop lights.  After further
tests, I did a compression test and found #1 at 30, the others at 130-140.
Had the valves replaced about 5,000 miles ago.  Assuming bad valves, do all
4 have to be replaced or can just the bad one?  Further, based on the
compression test, could it be bad rings on the cylinders and not the valves?
