Never Ending

Just finished the EGR delete and installed a new oil cooler last night. Now she runs like a dog. Running really rough at about the 1800 rpm. Don't know what to think. Took her to the dealership for a vc-9 coolant flush (I think thats what it is called). I did plug the egr valve in and its not throwing any dummy lights on. Any ideas?

Did you check your y pipe that goes into the turbo. When I did my egr delete oil cooler ect... It ran rough. That was because the y pipe wasn't seated. Take off the clamp and see if it's sitting on there right.

What did you plug or delete? EGR cooler right? Just egr is fine but doesnt do anything for the issue....EGR cooler.

Sounds like you have an exhaust leak.

I checked for leaks, could not find any. Builds boost like it did before so I think the Y-pipe is seated. Or I am I wrong for thinking that?

Do you have a boost guage?

Yes. Just the factory one. I am looking at getting either a programmer or a monitor to watch what is going on with my truck. I keep hearing that programmers screw up injectors and can give you truck more problems. Still researching though.

Just start your truck and stick your hand by the up pipe and feel for air coming out. An easy ways to fix it is loosen the three bolts on your turbo and loosen your up pipe and make sure your turbo has a little wiggle to it then tighten your up pipe back up and tighten your turbo back up then check it again with the engine running and the leak should be gone.

Update: picked the truck up from the coolant flush and everything seems to be running fine. They told me pretty much to drive it like I stole it for a while to clean out the intake manifold and exhaust side of turbo. But now I'm throwing the egr code. Even after I plugged the egr valve in to try and trick the computer. Didn't work. Now I have to get a programmer. What do you guys run with? And do you like it? Has it caused you any problems? Thanks in advance.
