Ok I need your help!! My mom and dad let my sister use my moms Sonata (big mistake, my sister and her bf know nothing about cars) well first problem is they decided to put an aftermarket cd player in (her bf who works at Car Toys did it, he knows nothing) well he wired it wrong to where it blew a fuse and will never store presets, well they decided that cuz the stock one was better to put the stock one back in (it wont turn on and the automatic door locks dont work anymore) and it wont work cuz of the anti-theft program on the car (it has to be reset by the dealership, I know!!)

Well it also started driving funny, it wont rev up past 2500rpms has a constant CEL and it jerks badly! They called myself and my bf (wilburisthecoolest, or wilbur or nick!?) and we told them to check the spark plugs, and wires and to get the CEL scanned at a schucks or autozone! Well come to find out my sisters bf was driving my moms car that night and was driving crazily and using the shift-tronic to shift up and down thru the gears really fast!!! Can I please get some help!!! My mom and dad are not thrilled with my sister and I dont know the Sonata well enough so I come to you!! Thanks

 

Get the codes scanned.

Find and replace blown fuse.

Report back.

 

Nick and I told them to scan it, dont know if they did and it sounded like they replaced the fuse!

I kno the anti-theft is gonna be something the dealership has to do it but as for the other stuff I have no clue what he did to the engine!!

 

It sounds like there's either another blown fuse or a problem with the wiring for the stereo install based on the PDL not working anymore. Does anything else not work besides the PDL and the factory stereo?

As far as the poor running condition like I said we'll need the codes.

 

As far as I know thats the only two items not working, I guess from what Nick says the PDL and the stock cd player thats the anti-theft system cuz they are tied together into the car (they're wired together for the most part!?!?) mad.gif
