If it's blinking it means there's a misfire. A-Zone can likely tell you what cylinder it's on and then you can swap the plug wire or coil from a good cylinder to see if one of those is the culprit. If it is, the misfire code will more to a different cylinder

lol, you posted when I was typing
I think all the O2s are the same, it's likely a plug wire connection. make sure you got them all plugged in good

my friend accidentally plugged his rear O2s in the front and the only thing it really did was make it run rich and his gas mileage sucked really badly, im talking 150 miles a tank. i could see it fouling up some plugs if you did this and that would be the worst case i think, but you never know.

a blinkin light is a missfire. re-check all plug wires and check the plugs. thats or a fuel injector. maybe a wire was barely on and when u hit wot it kicked it off... where are u located?
