my truck has been running like crap since this summer. Tey said it was EGR system so they cleaned the system and closed it up and its run fine for a few more months maybe, then same thing, and they clean it again and say if it does it again I should need an EGR valve.
Well now its knocking after my last oil change I think. So I replaced the EGR. But then my acceleration went to hell, and it still knocks. So I unplugged the EGR connector and acceleration came back, but now occasionally hard to start, and it still knocks. Or maybe its a ping?
I think maybe I got a bum EGR valve. Any other ideas?
Also heat occasionally disappears, and temp gauge climbs up toward 210. Then it comes back and heat drops back down a bit. I just had it flushed (it was nasty), but it seems to have a small leak.
only about 140,000mi on it and its 2wd.
