The rpms on my 2006 dodge grand carvan goes really high before shifting

I replaced the EGR Valve ($80 after tax), problem solved, vanruns great now. Now my problem is that I can't get the light to turn off.

I had the same problem on my jeep come to find out it was the crank sensor not reading the motor runing

SOURCE: How do you replace a

before you start you need to make sure that you have the sticker with proper routing of the belt to install the new tensioner and if not make a picture of it this will save a lot of time. next if you haven't already purchaced your part i would recomend any auto part store it will be cheaper than the dealer.most tensioners can be removed with a 3/8 or 1/2 ratchet or breaker bar to fit into the slot on the tensioner. pull one way or the other to release the tension and remove the belt off the pully then you will need a socket or wrench to remove the pully then install new part and belt, check to make sure belt is on all grooves and pully before starting.

ok i just replaced mine to but you have to make sure that you replace the throwout bearing(correctly)
if this does not happen it is like the clutch is engaged partially all the time and another thing is that make sure no oil is in the clutch pack. i replaced my main engine seal while i had it apart because it was tossing oil into the clutch area.

Good Luck

as you know the front ones are rather easy to get to, but the rear bank is a bear..the best way is on a lift but you can get to them using a 3/8 rachet a 3inch extension and the plug socket.. take the air tube off the throttle body.. reach under the throttle body behind the engine you will feel the plug wires that way.. once you get the wires off the plugs are a pain but changable..
