Lacking power, vibration at high RPM, rough idle
Hey guys,
I have a question about my 2006 6.0 PSD. Did a little searching and cant really find anything.
I was heading down the interstate and passed a car and right after I got passed, I noticed a somewhat bad engine vibration at 2000-3000 rpms. When I got out of the gas, the truck smoothed out. I was doing about 75 mph and could hardly read my fuzz buster clearly. Pulled over the the side of the road, thinking it might have been a u-joint or a tire or something, it wasn't. I revved up the motor and still could feel the vibration.
I have a scan gauge 2 and egt gauge, no chip/tune, all stock motor but 4 inch turbo back. My egts were normal, water and oil temp were normal at 185 +- a few, Ficm was normal at 47.5-48.5. The value that I noticed to be way off is the ICP. At 2000 rpm, it was only reading 94-103. From what I remember, its normally in the upper 230/240 correct. At idle its showing a value of 34/35. Again normally 46+ correct. I looked at the IPR and its reading 22.2-23.0 at idle, dont know what it normally is or what it is while driving.
My question is what would cause this ICP to be this low, but not throw a code, still hot start, run and idle.
Saturday I did an oil and filter change and changed both fuel filters.
Thanks in advance,
Andy
