Threw a P1404...
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. 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?
No wonder the thing was runnign bad. My question is how the hell did a rock get in my exhaust system??
