1992 Pontiac Grand Prix 3.4L Poor Idle Quality, Misfire
This vehicle came in with cylinders 1 3 & 5 down to 60 lbs
compression. It had just had a timing belt put on about 2
months previous. The first thing I did was to check the
valve timing , and found that the rear exhaust cam was out
by 2 notches .
