Hi all I just got back the car from the installer with the new cc 503 224/230 cam, cc 1.6 roller rockers, intake port, and the cc high performance valve springs. Well guess what I got a check engine light on the highway on the way home. Code p400 egr flow. what can it mean? Also my car doesnt have the as nastey sound as the 224/230 sound clip in the message board? Can it be I dont have headders yet or a gutted cat? thanks to all

 

did they hook the EGR back up? maybe they unplugged it and forgot to plug it back in. or they could have deleted it totally and blocked it off.

 

Not sure if egr is plugged in I'm going to check it tonight. Maybe he forgot to hookup vacume line

 

someone also told me that if everything is hooked up correctly it might need to be programmed(pcmforless) is this true?
