So im driving down the raod on a little cruise and all of a sudden after an hour and a half of driving the SES light Goes on. so i turn the car off let it cool down with the fans on high and turned my car back on and its still on.
Could it be because i have the Egr/air block of plates. but i only used two plates on each exhaust manifold not the tube that leads to the intake.
i just changed my spark plugs and wires a few days ago.
Anyone ??? please help
