looking for any ideas on this problem. 2007, 1500, single cab, 2WD, 3.7L, manual 6 speed, here is the issue when ready to shift up if you release the throttle and depress the clutch the RPM will climb some. so for some reason there is a delay in the throttle/RPM response. If I release the throttle and wait a good second before pushing in the clutch then the rpms come down. It has one code PO440 which is for the fuel tank vapors, I wouldn't think that would be related. Any help on this would be appreciated.

When you push the clutch in your going to get some rise in rpms as the load is being dropped off the engine. There is some considerable inertia in the lower half of the engine.
It's possible there is some drag from the transmission causing it, not likely.
Does the problem seem to happen more when the engine is cold? it could be the ECM adding fuel to warm the exhaust system up to operating temperature.

it's all the time, and it's more then normal as I've driven manuals all my life, currently a manual PT cruiser which shifts normal release the throttle and pushing the clutch shift, this pickup you release the throttle count 1001 push in the clutch and sometimes the RPM will want to increase before they drop, if you shift normal , release throttle push clutch rpms go up shift release clutch and you can tell the rpm is drug down by the engaged clutch. something is causing a delay in the throttle response. ( like a sticky throttle cable that the return spring struggles to pull back)
