A36. a cylinder balance test is being performed on an engine to determine which cylinder is causing a miss. Tech A says that when the faulty cylinder is disabled, engine rpm will drop more than for the other cylinders. Tech B says disabling the faulty cylinder will cause the engine to stall A B Both Neither {Ans: Neither the faulty cylinder will not cause the engine to stall, neither will it cause the engine to drop in RPM since it is faulty.}A81. the customer says that the engine requires excessive cranking to start. the LEAST likely cause of this problem would be: cracked cylinder block jumped timing belt faulty fuel pump stuck-open EGR valve {Ans: cracked cylinder block}35. the customer complains that the engine cranks but does not start; the first thing to check should be valve train operation battery voltage compression engine vacuum {Ans: valve train operation if the engine cranks properly, the battery is not the problem. Compression would not be the FIRST test, and because engine vacuum is low during a crank, a vacuum test would not be conclusive.}A99. a low, steady vacuum gauge reading from 11 to 15 indicates: burned or leaking valves
