hyundai tech .. my 01 accent problem has been solved
 

well man 2 weeks ago i got annoyed by a buzzing item in the engine
compartment which i had to listen too while testing sensors

i unplugged this sensor and said what the hey imma try it around the
block .... and it worked ... few days later i pick up a new idle control
actuator from the dealer ... installed it .. gave it more than a week of
testing and that was the issue

no check engine light and everything has been great ....

thanx again for all your help and hopefully you will never come across
this again (the whole seemed rev limited at like 2-3k rpm) but if so a
quick unplugging of the idle speed acutautor (right by the TPS) and a
spin around the block will let the person if its the issue or not ...

thanx again and hyundias support rocks

later jerry
