2008 F250 6.4 Hesitation/Smoke Issues
Apologies first for possibly reintroducing this question without full bore research of all threads, but here we go.
I have an EDGE CTS monitor I purchased to isolate problems I recently had with ECT and EOT. That resulted in replacing the oil cooler. Ugh!
Using the gauges in the CTS, I am now noticing that if I suddenly accelerate, no matter the speed, the engine seems to hesitate with white smoke coming from the tailpipe. It happens no matter how long the engine has been running. I use the truck only for commuting--no towing at all.
The gauges show engine load at less than 50%, 20 psi turbo or more and I get the Exhaust Back Pressure indicator maxing out at 40 (It flashes 40 in red on the CTS) and the regen light blinking. I also experience a power loss. I usually back off the pedal and accelerate more slowly and the problem goes away.
Now I noticing if I have to go up a very steep hill at lower speed/pedal pressure, the same thing happens, like the engine is maxing out and not able to pull like it should.
Any clues on what is happening? Or what else I should be monitoring?
Many thanks in advance.
