Guru, my engine light is on, if I install the new master airflow sensor will it go off , or should I have it cleared first.Thanks

Thank you, I had it scanned , it read running to lean, erg was just cleaned out, not wanting to spend more money the tech suggested the MAS to be replced, that code I believe was 4206 for erg, thanks

THANKS, I will get the actual code, I MAF WAS filthy full of soot with no apparent vaccum inside the airintake box, I did change it now its vacumning away, I hope this ends the nightmare of the Engine light, if not ill be back, thanks for your time.
