Newb question: Funny tach. reading.

[T-ROD]

Im new to diesels in general and this morning I was bored so I was playing around on my way to work. My truck was warmed up to normal operating temp when I did this by the way. I was on a straight stretch of road and in second gear. I pulled it up to about 2 grand held it there for a second then pushed it to the floor to see what would happen. When I did this the tach. jump up maybe 100 rpms (moved like a 16th of an inch) then came back down to 2000 and took off. Is this normal for a totally stock 97 PSD, with 3.55 out back?

Is it an auto or stick? Sounds like either way it's the TC slipping or the Clutch slipping.

Its a stick. It just had a new clutch put in it last summer, and wouldnt it jump up more than 100rpms if it was slipping?

It depends on how much it's slipping. It could be just slipping a little bit causing the problem...OR...I could be 100% wrong on the problem. I replaced my clutch in March of 06 and I've slipped it a few times. (Got that tell-tell clutch smell.) You might have over heated it a little causing it to slip. (That's what I did.)

Could it be the throttle position sensor. I just remembered for the first 1/3 of the pedal nothing happens then it finally feels like the pedal is doing something.
