Coolant Puked. EGR valve wet/loss of power and smoke
So this started last week. I was running stock and and the pedal went to the floor with no response. It then started to shake, and smoke like crazy. I'm not sure what color it was since it was pretty dark but I am going to guess white.
Code P0404 came up and is the EGR. I took it out, cleaned it and put new o rings on. Truck still was running like crap. I put the Xstreet tune on and it seemed ok. I didnt get on it since I was still nervous.
On the highway the other day and started to step into the throttle, and it puked. I came home and set the truck back to stock. It has been running like crap since.
Tonight I changed the oil and fuel filters thinking that may be a problem. Well that wasnt it.
I pulled the EGR back off and found it to be wet at the bottom of the opening.
I have done some reading and sounds like it may be the cooler. Sound about right? Is that covered under warranty?
Truck is an 05 with 53k on it.
Thanks in advance.
