Are there any portable engine diagnostic devices, such as CarMD that are legitimate, work and are affordable, and if so, which ones do you recommend? Thank you!

With CarMD, you are not paying for the device, you are paying for the expertise of technicians who see what your device sees and provide you an explanation and recommended course of action to repair any problems, along with estimates on what a repair should cost.
You can buy code readers and scanners starting at under $50, but if you don't understand the meaning of diagnostic trouble codes (DTCs) or what you should be seeing with a scanner, it doesn't make too much difference whether you spend $50 or $1000.
I don't have CarMD, and know nothing more about them than what I see in their adverstisements, but it sounds good.
You could go to most auto parts stores, have them check your car for codes, and they will probably recommend you buying something that will 'fix it'. Or, you could have them give you the code(s) - get a print out or write them down. Then research yourself, or ask a knowledgeable friend for help.

The P0456 is not your cause here. If there are no other codes present other than the P0456, try unplugging the mass air flow sensor and see if the sputtering goes away and if so, replace the mass air flow sensor. You could also have a clogged fuel filter or a bad fuel pump (low pressure)

My CarMD Report shows a P0442 Error Code on my 2002 Hyundai Accent GL My gas cap is on tight but, not sure about the seal. I have 8 possible causes from the CarMD Report. What do you...

Ouch. thats a tough one. Your fault code is for a small EVAP leak which is notoriously very hard to find. I would follow the most likely causes from the CarMD report. They are generally very accurate and based on input from technicians like myself. Remove your gas cap and inspect the seal around the cap. A leak as small as 0.02 inches will trigger the code you are getting. Literally some dust or debris could cause this. I would inspect the seal for cuts/tears and clean it. Replace the gas cap is the cheapest thing to try first and the likely culprit here. Check CarMD site for recalls and TSB's regarding EVAP leak as well. Good luck.

Hi There! After pulling the code from your CarMD did you plug in your CarMD device into your computer?
CarMD will search through their database with your specific make/model and the error code being generated.
