First check for a loose hose or a vacuum leak. If you do not find a leak most likely the throttle position sensor is stuck and causing the truck to idle high. The throttle position sensor sticks, and if this happens you will need to replace it.

The concern happened after you relaced the plugs? You need to look for a vacuum leak that may have been created during the install.

2007 Dodge Durango. Idles at 1500-2000 rpm's and stays high even when in gear. I have replaced the IAC sensor and TP sensor and can't hear any leaks. What could this be??

Did you check the throttle plate to make sure it is closing completely ?
The tps only tells the computer what position the throttle plate is in.
A vac leak could be very tough to find, especially if it is a leaking intake gasket or EGR valve if equipped.

Probably a vacuum leak at the intake manifold,or an o-ring at one of the injectors.
if you spray carb cleaner around the sealing edge of the manifold and at the injectors and the idle changes ,you found the leak.
The plactic intakes are prone to this problem.

2004 Dodge Durango. when started it idles high to 2000 RPMS then when on the road it stays at an rpm, you dont have to push the pedal it just goes by itself.

It sounds like the Idle Air Control Valve is stuck. This will give you a fixed idle it can stick at high idle or low or anywhere in between. If you take off the air cleaner you see where the air is getting sucked into a small slot or hole. spray some carb and choke cleaner in there let it sit for about 5 minutes then start the engine. spray a little at a time with the engine running till the idle comes down by itself. This should take about 2-3 minutes. If it wont come back on its own take the 2 torx screws out and remove it clean with carb and choke cleaner and replace. If it still fails it will need to be replaced. MOST of the time cleaning it will work

Dodge durango 2000 stop runing at20to55mi.per hr.

The fuel filter is clogged. This will restrict fuel pressure, not allowing the engine to receive the proper amount of fuel thus choking the motor. If this was at all helpful, please rate. Thanks for asking.

I push my clutch in on my 03 neon sxt and it will not go into gear while its runing but will go into gear while its not runing

It sounds like your clutch slave cylinder is not working. Check clutch fluid level and try bleeding it. If that doesn't work you will need to replace either the master or slave cylinder.
