i have a 98, hyundai accent 4dr ive been in posession of for about 2 months now
at first it seemed to drive ok maybe for two weeks or so then i noticed the overdrive was on and since i live in the city i figured it should be off unless going up hills so i turned it off. also around the same time i turned off overdrive, i installed a new car stereo myself which worked fine for about a week and then stopped outputting sound..??

my issue however is that roughly around the same time as overdrive coming off and my stereo not making sound, my car started to rev really high when i was driving, it would happen when i was stopped and starting to accel and sometimes it would happen as im comfortably cruising along at 60km (in canada here)
from there things started just getting progressively worse, i dont know anything about cars and this is my first one so i tried turning overdrive back on which at least got rid of the check engine light (temporarily)..
after about 2 weeks of it revving up really high whenever it felt like it, it started to act up really bad in the mornings when i started it up
for the first 10 or so blocks in the morning when im stopped at a stop sign or red light with my foot on the brake, you can see the rpm jump up and then drop repeatedly and you can see the car rock slightly as well as feel it...
this usually went away after about 10-15 blocks of driving the car so i just figured she doesnt like being cold
i was advised by my roommates father who is a mechanic way out of town to get my tranny fluid changed if it doesnt look good so i went to mr.lube and had them change my transmission fluid and my oil which at first seemed to make it worse but now i'm not sure.. immediately after driving out of mr.lube it was really jerky but it seemed to calm down after driving for a while

then last week i was coming home and stopped at a red about 8 blocks from my place and when the light turned green, i started to accel but the car just revved slightly and then dropped down repeatedly which made the car rock back and forth quite violently to the point my passenger thought we were going in reverse.

so i managed to get the car home and it is sitting in my lot the check engine light was on but i got a reader and when i plugged it in and turned the car on the check engine light was not on but there was one code stored, 0442 which i looked up in my manual and it says its the evap emission control system

again, i dont know anything about cars, im a computer tech lol, has anyone encountered this? the manual says the evap emission control system consists of 6 or 7 different parts and i need some kind of hand pump or something to check the parts but i dont know if its better to just bring it in somewhere... and i've never had my car in anywhere so i dont know where to bring it so i dont get fleeced...

any suggestions would be appreciated.. thanks (IMG:style_emoticons/default/smile.gif)


oh ya i forgot to mention it stalls too.. if someone cuts me off or the light changes and i have to press the brake really hard to stop fast, BAM.. stalled
