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?
