I'm getting a P0403 EGR solenoid circuit code on my truck. It started about 2 weeks ago occasionally and has been tripping more frequently. I can clear it with my tuner it doesn't seem to be down on power when it does trip.
Any info on how to fix this problem with out breaking the bank or taking to a Chevy dealer, or getting too crazy with mods.
Also about a month or so ago I got the low fuel rail pressure code, truck would go into safe/limp mode and wouldn't turn over 2k RPM. That issue was fixed with a PPE race plug. Not sure if the two issues are related.
