Yesterday I was pulling a trailer with a small load on it. I went to climb a hill and noticed some lack of power, looked in mirror and I was rolling coal big time, the truck seemed to surge a few times, and it popped a couple times under the hood (like a backfire through the intake?).
Seemed to do ok on flat ground afterward, hit another hill and same thing as before.
So, after some reading I am pretty sure it was the EGR valve. I cleaned the EGR about 15k miles ago and it didn't look to bad then. So, I figure it has failed and I replaced it. Circle around the neighborhood, same problem!!
I decide to unplug the EGR and give that a go. Guess what? No smoke, surging, popping etc. I know some guys run with it unplugged. But I would at least like to hunt down the problem. Where should I look next? I am thinking EBP sensor and tube maybe?
Any input is greatly appreciated.
My truck is almost bone stock.I had all 8 injectors replaced and a new FICM a couple months ago and truck has been doing great since. HPOP was replaced about a year ago. I have noticed a slight surge when at idle on occasion, and sometimes has a long crank, if any of that helps.
Thanks guys!
