i just had my problem with check engine light and trac control removed.... P0171.... I was thinking to go to dealer and have code verified, but decide to do what my friend told me. "clean mass flow sensor with spray cleaner"... First I though I have to replace O2 sensors and spend 300$ for parts and service, but cleaning this sensor fixed the problem. this is the link http://www.lexusownersclub.co.uk/knowledge...id=152&c=11 Total cost of fixing the problem = 6.99$ :D :D Thanks , cleaned the MAF but the code popped back on after a few miles. Can someone tell me how many MAF or 02 censors this 1999 es300 has and where they are located at ?
