this is my first time ever posting a thread on any forum.
i love this forum its full of people that are experimenter and are not afraid to try something new, so any help with my question will be greatly appreciated.
i installed a hho generator on a 2000 exterra and the moment i turned on the car i noticed it ran alot smoother and i am getting better mpg's which im really happy about but my check engine light turned on. i went to autozone and i retreaved 10 codes mostly form the map and 02 sensor. i wanted to know if anyone elses car has set off the check engine light from just installing a hho generator? should i worry about this?
