Ok. When the Check Engine light blinks, this is "Random Cylinder Misfire". Which means the on-board computer sees one or more of the cylinders aren't firing correctly, but it doesn't know why... yet. When the light turns solid, the on-board computer now knows the root of the problem. Unfortunately, there are many things that can cause a cylinder misfire; worn spark plugs, a faulty ignition coil, a faulty fuel injector, etc... So, at this point, we'll need the Diagnostic Trouble Codes (aka "P-Codes") scanned from the computer. These p-codes will more accurately point us in the direction of the root of the problem. You can have these p-codes read FREE (except in California) at any local "big chain" part store (ie. AutoZone, PepBoys, Advanced, etc). More commonly here will be plugs, coil or injector.

Hi! I noticed this thread was still open, so I wanted to check in and see if there was anything else I could do for you on this issue? Any other questions you had? Was there something you wanted addressed that I may have missed in my answer? Did you find my answer helpful and informative?
