got a code P0402 from the computer this morning for the CEL. egr excesive flow at idle
we know we need to clean the throttle body and egr passages behind the throttle body. should this take care of the problem?
it is the 99 SE Sport that we just got. Has 52k and was driven fairly easy. I had gotton on it a few times last night and then the light tripped when I was sitting in a line a traffic. I think some junk got stuck some place because the CEL turned off this morning.
