Hey there. You should probably have another look at your plugs and wires to see if the work was done correctly. Something may not be well connected causing an intermittent misfire. The Check Engine Light comes on steady when the computer detects a misfire or other malfunction. If the Check Engine Light is flashing, it means the malfunction is bad enough to cause damage to the catalytic converter. If you are equipped to read the trouble codes, they will tell you which cylinder(s) the misfire was detected on. That will help speed up locating your problem.

If you are not equipped to read the trouble codes, you can contact YourMechanic to come and scan it for you. They can diagnose the Check Engine Light and misfiring symptoms so that these issues can be resolved.
