Vaccum issues help

[90stepside]

Hey guys I have a 1990 Chevy k1500 with the 350, it's been my project for about a year now and I'm getting around to getting the motor I installed tuned in, my issue is when I hook the egr vaccum line to the map sensor the motor chugs really hard then dies. The egr is new too. anyone have any idea why this is happening?

For anyone that is interested I figured the issue out it was a bad map sensor

Good to hear that you solved the problem. HOpe the truck performs up to your expectations. The 350 is a great engine.
