1995 5.9 magnum EGR disconnect
Have a 95 5.9 magnum that the shop just put new short headers on. The old shorty headers had the egr hookup. The new ones don't. The mechanic plugged off the egr thinking it should run normal if doing so. The truck now runs like crap. Stutters at cruising speeds and slow accelerations.
I learned by calling a dealer that this is a California truck (I inherited this truck from my grandfather in Oregon) and therefore has a cali programed computer.
The question is, does the egr in this particular truck talk to the computer and be the reason for the stuttering/misfiring problems? The mechanic is convinced that it's not the egr being disconnected causing the issues and it's something more in depth. The truck was running perfectly before the header swap, there was just a small exhaust leak because the header was slightly cracked.

If the EGR was blocked off properly, you should not have an issue. You can see an example of an EGR block off here - see the plate on the intake with the two bolts - https://dodgeforum.com/forum/2nd-gen...snapped-3.html

The EGR block off plate is pretty easy to make if you have metal and tools available or it can be purchased here - http://stores.hi-potek.com/egr-block...take-manifold/

I was just about to link the pic showing the EGR blocked off intake from the other topic. I thought it was odd you can apparently just leave that big back hole sitting there open, only need the blockoff plate, gasket I'm assuming, and two bolts to screw in where the EGR would normally sit.
