front to back, Drivers on the left, is
186------------183
155------------195
170------------180
150------------180
195 is an anomaly so throw it out
150/155 on non-adjacent cylinders are indicating a problem.
the average of the best four, not including the anomaly is 182.25. Therefore, 150/182= 82.4%, equals 17.6 % low, and all on the same side.
Couple that with the thousand rpm idle and the pull-back, this is all pointing to one of two things; A bad driverside head or a bad cam. The LD will tell you which it is. If you got rocker-clatter on that side then you already know the answer.
