Threw a P1404...
Hey guys help me out here... Heres the scoop. Since the weather was nice today id figure id get my car and wash all that dirt off.. and I didnt wash the engine either... So after I finished getting my car cleaned up I went for a short drive to the store and back. When I pulled into my driveway, I let it coast without touching the gas.. to keep from getting it dirty again and I notice that it seems to be "missing" a bit. So I pull it in the shop and now its really missing purdy good. Sounds just like its got a cam in it And it doesnt lol. I rev it up a bit and seems to be missing at part throttle. Then the SES comes on. I hook up AT and only code is P1404 EGR Closed Position Performance. Could there be some carbon up in the EGR valve? Would that cause it to be missing so badly? Oh and it doesnt crank back up too easily either. I have to give a bit of throttle to start. Any ideas? Only mods are the SLP headers and cats.

does it run alright off idle? your EGR is definately clogged/FUBAR. you may try tapping on it while it is running, that may loosen up whatever is holding it open.

I'm gona take a look see here in a bit and see if its stuck open or whatnot. Would carb cleaner be safe to clean it with?
