So, this was my last resort... But I gotta figure this out.
Got an '03 2500 with about 180k on it, nothing aftermarket performance-wise.
This is my first diesel, and I'm still soaking in the information so here we go..
I recently started getting a surge when I'm slowing down. Been at 50+mph, slow down to a light, and as I stop the engine surges. The whole truck doesn't surge, or shake or anything. The engine just sounds like it's about to stall, then at the last second catches itself, then does it again and again until it finally gets back on time.
Had a buddy take a look at it, he thinks it's the injectors because even in park, the truck still runs the revs a little, then idles normal, repeatedly. We got a scanner on it, but it wasn't one of the big money ones so all we could get from it was that my MAP sensor is bad.
Now, assuming that it is, in fact, the injectors and I go change them with say some 15% over injectors, from what I understand that means I need to use different injector inlet lines, and the ones I saw on XDP require you to run different fuel lines.
With all of that being said -
Part of me thinks it might be the Torque Converter, based off of things I've read here on the forum... thoughts?
If I run 15% injectors, does that warrant the necessity of a lift pump? I understand that lift pumps are needed for certain things, but I can't figure out if it's really necessary for 15%.
Would you all agree that the issue is the injectors?
I ordered the new MAP sensor, figured I'd start there.
Any thoughts/opinions/ideas would be awesome.
Thanks in advance.
