My engine seems to run fine, at idle its very smooth and no unusual noise, albeit a little louder than I remember.
When driving tonight, without the sound-system blaring, I listened to then engine almost deafening "clacking" & "clatter", what I would describe as a horrible case of "pinging" if it were a gas vehicle. Then engine has good power, can hear a strong turbo whine, no smoke, good oil pressure & stays cool. As I was driving, I started changing the throttle pressure and speed to see/hear what would happen. Under 2000 rpm at 55-60 mph the clatter is not that objectionable, but once you go over 2000 rpm its almost as if a switch is hit and the "clatter machine" turns on. When you release the throttle, all is quite & smooth, but once you hit the throttle again you get a burst of clatter then it settles down, but not much. I also had a weird phenomenon of the engine or IP acting like the trans has shifted into overdrive, yet the rpm's stayed that same, but the vibration and clatter reduce. Is my IP about to explode, is there a bad injector(s), bad line(s)is it something other than the IP?
I did notice that two of the injector lines seem to be touching on the pass side, seems one of the mechanics lost some of the brackets on the right side that hold the lines into place, is this critical should I place some sort of insulator between the two lines?
Dang I wish there was a mechanic in the Dallas Ft Worth area I could trust to look at it and diagnose it properly (and at a reasonable cost would be nice) Cant afford to get stranded while on the freeway with this Suburban again.
