How do you know?
Sometimes the vent is clear but the vent louvers are not opening correctly.
Also check that the lint filter is not coated in fabric softener residue which can greatly reduce air flow through the system.
You may want to try the following:
Undo the dryer from the exhaust
Run a load
If the load dries correctly then you have a vent problem.
Clean/check the vent system. Make sure the outside louvers open fully.
If you do not want lint in the house.
Take a pair of pantyhose, put one leg into the other and attach this to the dryer exhaust.
Leave enough room behind the dryer so it can blow out like a windsock.
Run a load.
Both the above will allow you to check the air flow and temp.
Also the above is NOT recommended for a gas dryer due to possible carbon monoxide problems.

I ohmed out the heating coil, but i think i may have done it wrong, I removed the heating coil, disconecting both leads and put the digital meter probes on each coil lead and got a reading of 9.4ohms.[/COLOR]
This sounds OK.
When you had the heater disconnected, you should have also checked from each side of the heater to the frame. Both. should be infinite (open) ohms, if not you have a grounded element.
[COLOR="Blue"]One thing i noticed this being a dual sided coil that on the front coil abou 3/4 of the shield was very dark, the remainer of it was just clean as could be on the heat shield.[/COLOR]
Probably OK. I would check the interior of the heater case for any signs that the element has been touching the case re: arc/weld marks. Sometimes a heater will heat up and sag causing a problem.
[COLOR="Blue"]Could this be a coil taht under operation starts out hot then slowly fades or could it be the thermostat that attaches to heating coil heat shield,[/COLOR]
Both are possible.
The thermostat which is the hi-limit is the less likely of the two. They usually go bad by either welding their interior contacts closed or never closing.

also about 12 inches above the heating coil it had another sensor[/COLOR]
This is a thermal fuse. It will be OK as once it blows it stays blown.
[COLOR="Blue"]do you think the element is going out or is thier other issues[/COLOR]
Could be a number of things.
Try the unit disconnected from the vent just to confirm that the vent system is OK.
Clean/check your blower wheel.
Try the unit on a low heat setting to see if it runs the same.
If all seems OK then the element would be at the top of my list.
Also could be the operating thermostat which is on the blower assembly.
