I just changed my plugs and when I finished I started the car it was running rough and the engine light came on. I heard a constant ticking noise and look under the hood. One of the wires was loose. I made sure to put the wire back in tight and started it up again. It ran pretty and sounded pretty good. Every thing seems to be working fine but the light still comes on.

Any Ideas????

 

you have to clear the code off the computer. it stores them and keeps the SES light on.

pull the battery cable for 10 mins or so...should be fine.

 

it should go off in a day or two

 

If it was a P030X (misfire) code it should turn the light off after three consecutive starts if the problem is gone, but will still stored in memory for a while.
