I am starting to wonder if my egr system isn't working, i know the ports open and close freely but i am wondering if my "hesitation" problem is resulting from little to no backpressure in the exhaust system is this possible?. I never had the "hesitation" or "miss" untill i put on the new "unclogged" mufflers.........hmmm. Plus the Catylitic converter itself is questionable..... I guess i'll wire open the 5th and 6th and see what happens... Do you just take some wire and hold the plunger in the down position to open the ports ? Is that all there is too it? Thanks for the help..... trevor
