I have an 07 3.7l club cab 6 speed. When i have it in neutral and rev it up ( for some nice sound ) it takes forever and a day for the RPMs to wind back down. is there anything i can do or replace to keep from this happening. Thats probably the only thing i dislike about the truck. Does anyone else have a V6 that does that?

 

its because you have a clutch fan, remove it and install an efan.

 

Explain please....

 

I doubt it's the clutched fan - it would only serve to drag the engine down faster when your foot is off the gas.

My '07 3.7 V6 also takes a long time to rev down, particularly on cold mornings. I've just chalked it up to the electronic throttle mapping. The throttle body is always a beat slower than the gas pedal, both getting on the gas and lifting off.

2007 was the first year for electronic throttle on these trucks.

 

No offense, but that does not have much to do with a "hanging" decell of rpm speed. My 3.7L did not do it with the factory clutch fan with 80K on it, before I went to the e-fan.

To the orginal poster: I think Cramerica is right, look into the electronic throttle stuff. My Dak is an 06', last year of the "real" throttle cables.

 

I know alot of guys with manual transmissions had problems with the RPMs hanging between gears when they had the V6 ..... and guess what the dealer said! Normal operation! I don't agree that hanging RPMs are normal though.

 

well when i had my clutch fan on it had the same problem, i took it off and it was much better.

 

Well i guess i could unhook the clutch fan to see if thats it. I was looking at the fastman throttle body, would that take care of having the throttle body concern? or do i need to do something else?

 

Are you guys sure about 06? I am pretty sure mine has a cable all the way through... 08s were the first of electronic throttles. I mena it does have the same TB.

 

yea i think 08 is the first year
