Engine only runs at idle

If it's a Chrysler/Dodge product, disconnect the battery for about 10 minutes and re connect it. Try starting, be sure the battery has a FULL charge when you do.

Won't start but did and stalled out won't start at all now and oil filler cap smells like gas

If the oil cap smells like gas, one of the injectors may be flooding the cylinder and the crankcase. That would not be a filter problem.
Check the spark plugs to see if they are wet.

2001 PT Cruiser Limited Edition -Stalls 15 mins after starting. No Codes. Swapped out Auto Shutdown Relay, and Crank Position Sensor and harness- No change. New Alternator, Battery, and Starter. What...

wits end. my specialty.
first off intermittent are hard hair pullers.
but I find them all with patience and tools, and setting traps.
guessing is a waste of cash and time. stop that.please.
the first question is:
can you save it with your right fast foot, #1 top importance !
15 min just idling
only moving or both.. try to say when it happens.
in gear , out of gear. etc.

first off there are only 4 basics engine stalling causes.
1: lost power (12v) to EFI , any voltmeter can catch this.
2: lost compression in engine (bad engine) only hot. (gauge it)
3: lost spark. easy to see with any strobe light or $2 spark tester or actual spare spark plug..
4: and last, Bad fueling. staving or too much and flooding.
this is easy to find. look at all spark tips.
dry , starving, wet flooding. (1920- to now, no change)

i can not go past this until my First questions above.

there is no need to guess ever.
all the tests are simple and the tools dirt cheap.
less than 5% of costs already !

2002 Malibu stalls while driving, doesn't over heat. But can start smelling gas fumes before it stalls. usually wait about 5 mins then restarts. in higher elevation runs fine but in lower elevatio

It sounds like the catalytic converter could possibly be almost completely plugged up not allowing the exhaust to leave the engine like it should. It just builds up in the cylinder head and when it gets too much in it built up and there's no where to go, it'll stall the engine. By letting it sit for a few minutes, it gives the exhaust time to find a way out and the car will restart.

I would start checking crank sensors and cam position sensors. There may be codes present that are not readable by over the counter OBD scanners. To get the real low down on the problem, the vehicle needs to be hooked up to a MODIS scanner. Otherwise you are going to rack your brain and your pocket trying to figure it out. Especially if it's intermitent. There are just to many possibillities with all the modules and sensors that are in place these days.
