installed new O2 sensor still have problem
i had a bad idle and bad fuel milage i thought it would be my o2 sensor so i changed it i still have a bad idle (800rpm sometimes 750rpm) i didnt take the truck out yet so i dont know about gas milage does anyone else know wut else can cause this low idle?

if in fact u are running that rpm speed u are doing just fine.. that is normal... if it is wayyyyy lower like almost dying then keep checking around and i will see what i can see. also have u checked the TPS? May be that but if u are 750 800 u are right on it..

timing
o2 sensor
TPS
coolant sensors
are ALL major factors in loss/fuel economy
I have just went threw 2 years of 300K per tank woes .. replacing sensors , checking , tweeking .. ahhhh .. so I'm bald now .
I replaced almost every sensor .. EVERYTHING .. except airflow meter and computer .
I did some checkin' . I had the Original throtle body , which I cleaned , and thought I would set it up the TPS .. as per the factory specs .
problem is .. I cant get a consistant reading on the meter , because of the throttle shaft movement . my throttle body is toast ..
so I check all 3 that I have .. same thing .. I check the supra throttlebody im building .. no play . DANG ..it's perfect ...
I check with toyota .. part # 22210-35150 replacement .. NO LONGER AVALIABLE ... this sucks ..
sorry for the long wind .. but I forund a good throttle body ..finally .. set it up with my ohm. meter , and seems to work good now ..
3 days now and I have already noticed an improovement in my fuel economy .
