when I was reconnecting the plug connectors I bent the middle prong of one of the connectors.

I think this caused that cylinder to miss, throwing the CEL

I fixed the problem and the car seems to be running fine, I 'think' i feel a bit better response and midrange, as the previous owner had champion plugs in it. I put NGK G-power model BKR5EGP

My question is will the CEL correct itself?

or: how can I reset it?

Thanks

 

1.) Pull up the codes by using your ECM (search the FAQ's to find out how)
2.) wait 2-3 secs and turn the screw clockwise
3.) wait 2-3 secs and turn the screw counterclockwise
4.) Turn off the car

Drive around for 2-3 days. If it comes up again check the code.
