engine reving?

[machinemover]

I now have 35,000 on my truck, no boxes yet although I just ordered a tst box. I just noticed recently my truck reving in between gears, in other words I shift from 3rd to 4th or which ever and it does not de-cellerate like it should or let up as quickly as it did. It feels as if it is still feeding fuel. My rpm will stay at 2500 or my shift point, for a split second before de-cellerating. I first thoght it was my imagination or shifting habits changing but I don't think so. Is this a problem? Any one else notice similar symtoms?

I call it a problem. Dodge calls it normal. It does exactly what you said, continues to inject fuel after you have let off the throttle. If you get an EZ-Edge box the problem is worse.

could try the tps re-teach, don't know might work.

dont worry, its normal

It seems like it gets a little better with age or maybe I've just gotten used to it.

If I remember what I read a while back (I think it was even in the owner's manual?), when the CTD is revved to a high level and you push in the clutch to shift, the engine will continue to feed fuel This is especially noticable if you accelarate hard and shift at high RPM's. Under normal driving, I haven't had this happen, but if I rev up to 2600-2700 and above, I notice it.

RPM flare: a function of the HPCR due to the 23,000 psi.

I only notice it if I'm doing a full throttle run. Normally I let off the throttle early and shift well below redline. No prob.

I just turned 20,000 miles on my truck last night and it's never done anything like described here. It always drops RPM as soon as I let off the throttle in any gear. My truck was built March 6 2003.

guess I'll have to learn how to drive my truck all over again. I normally shift close to redline and shift quick. Habits are hard to change but I don't want to waste a clutch either. i guess this is just a rail pressure problem we will have to learn to live with. i would rather it be a problem like this then the $14,000 in repairs I put in on my 2000 with lift pumps, trans, injector pumps etc...

I think of it as more of an idiosyncrasy than a problem.

Or you can turn the exhaust brake on before you upshift and that will decrease the flare.
