What are the side effects of driving with the egr solenoid Unplugged?
I replaced my egr and my new one is doing the same thing the oild one was, so im thinking my egr solenoid is bad. I was reading on another forum for a diff type of car that if i just unplug the egr and cap it all off that the ECU will still shoot the egr solenoid commands that it can not fulfill, however upon unplugging the egr solenoid and resetting the computer that it would completely look past it, this was for that car, do our trucks work on a similar basis.
What is the side effects of running like this until i can find a new one for a price i can afford(have to love December), $60 is the best ive found one so far, if anyone knows where i could get a used one or have a used one please let me know. My junkyard doesn't have any of our trucks on the lot currently.

EGR dosnt work when idling or wfo. There is a power on sequence where the ecu checks the electronic spark timing; egr; and knock sensor. If it doesnt get back the right answers it will kick a obd code. The side effect will be a lot of detonation at part throttle operation. And possible short term fuel trims going

What will happen is when the egr solenoid kicks in to tell the egr to do its thing the truck will start stalling while at idle and running like ****, the second i pull the vacuum tube that leads to the egr it idles back correct, if i plug it back in it will go to **** again ect..
Thats why i changed the EGR to begin with.

Well apparently on my truck there is lol, if not pulling that hose off while its idling and running like crap would have no effect. Maybe the egr solenoid is in fact bad and sending bad info to the egr? When its doing it it nearly chokes itself out and sometimes does and goes up and down, almost as if the egr is pumping back and forth (same effect as when you compress the egr manually)
That hose seems to be in good shape
