Engine size?? makes a difference

Note: An ODBII diagnostics reader (4 digit code) would tell you the cylinder number having this problem instead of the generic two digit diagnostic code you have.

This error means you have weak spark to one or more cylinders.

In the 2.5L or 3.0L engine, this error means a cylinder is misfiring or not achieving maximum power for some reason (plug, wires, or something else).

In the 3.3L or 3.8L engines (electronic ignition), in addition to plug or wire causing a misfire, the problem could be in the coil corrosponding to the problem cylinder. The coil would be failing to send spark to the cylinder for the proscibed amount of time (i.e. dwell).
