well here they are p0402.......the pcm has determined that there is excessive flow in the exhaust gas recirculation system..
p1405... egr sensor or tube/hose off or plugged or egr dissconteced or plugged..
pp0420.... the pcm has dtermined that the catalyst system effieceincy for bank 1 is below threshold for the current engine operating, blah blah blah...
i had another one, it was a misfire in cylinder 4, but stupid me forgot to make sure the tube was connected properly to the spark plug after i jsut changed it, but anyways, this is very intersting, these other codes i mean, because i just had my egr valve replaced about a month or maybe 2 months ago at the latest, so i dont know what these egr codes can be, the guy at autozone said maybe cleaning the hoses out, but i have no idea if i should do this myself or take it in, i have the haynes manual, should i rely on it, to do it myslef? this car is really starting to piss me off, i want a svt damn it...any comments or suggestions would be great..
