Driving home from work today I noticed the orange check engine light on. I checked the gas cap since I got gas 2 days earlier. The cap may have been a little loose, not sure yet. When I started the car back up the light was still on. Is there something else I should look for before taking the car to the dealership?
Odds are that if you didn't do any work under the hood, you are going to have to get the codes read. In most of the newer cars even if it is the gas cap and you put it back on, you may still have to get it hooked to computer to get the code cleared. There really isn't anything else to check if you haven't had any maintenance done recently.

Many of todays cars have a mode called Limp Mode. The Motor and Computer talk to each other and if faults are found? The Limp Mode (( Short for Limp on home mode )) will be set in the Computer. Go to your local Auto Zone and ask them to Scan the OBD 2 fault codes with their reader. Or pay the dealer. It may be something really simple. My Check Engine light was on the other day because the Gas Cap was loose. This Scanner told us the problem and we tightened the Gas Cap. After 3 times driving the car with it tight .... The Check Engine light went off.
I'm not sure what you mean by "kick". But the gas cap light will not affect the performance of the engine or transmission. I would recommend having the computer scanned for trouble codes next. The gas cap light means the computer has found a vac leak in the venting system for the gas tank and it could be allowing fumes into the air. The most common reason is the gas cap has been left off or is not tight. But if you have replaced it the problem is elsewhere in the venting system. The trouble code stored for the check engine light would point a mechanic in the direction of the actual problem.
P0340 - Camshaft position sensor circuit malfunction.
P0457 - Evaporative emission control system leak detected (fuel filler cap loose/off)
There is a bulletin #0398 posted on 05/12/2003 for P0457 - Malfunction indicator lamp (mil) illumination with diagnostic trouble codes p0442, p0455, p0456, p0457, p1442 or check fuel cap lamp illuminated with diagnostic trouble code p0457.
I'd suggest checking with your local dealer, as it may be a fix that is covered by the dealer.
Yes...the cap needs to be on there or the purge system will register a leak. The light may not go out right away but usually will after about thirty miles of driving. (computer needs to go through a complete self test cycle).
If you allready checked the gas cap and its on right.
Try replacing the gas cap with a new one.
You should here air wen you open the gas cap after driving
This is part of the emision controls and if it dosn't seal it will cause the check engine light to come on .
Undoing your battery doesn't help, years ago it did clear the memory, but not on todays vehicles. You need to have it scanned. If there is no errors in your computer right now, after a bunch of starts (starting your engine, and driving) it will reset itself. It does sound like you have an issue that the computer has detected.
I'm having same problem on my 2000 model rodeo 4wd 3.2L V6. Other day check engine light came on. I checked engine bay nothing abnormal, or power loss. Next day light was gone. 2 days later driving, a sudden loss of power and light came up. After idling for a couple of minutes, drove off with light still on but all power back. 1 hour later of faultless driving loss of power for a minute or so. Engine temp normal. Had break for 1/2 hour and set off for last hour of journey without fault except check engine light still on. Following dayon startup light went out???
