Z19 INSPECT FOR INTERMITTENT MECHANICAL CONCERNS
Note: It is possible for an intermittent mechanical concern to cause a good PCM system to react abnormally.
• An inspection of DTC related mechanical systems should have been carried out in an earlier section. If not, visually inspect at this time.
• Look for possible vacuum lines, wires, cables, linkage or hoses that may become kinked, shorted or restricted during normal engine operation.
• This may include engine/transmission gear changes, acceleration and deceleration, rough roads and various engine RPM and torque related conditions.
