I have Lexus ES 300 Model 2001 purchase month back. I am facing two problems one is fluctuation in rpm when car is idle and even during drive i feel fluctuating in rpm. I replaced batter month back but now again it shows sign of replacement on battery itself. There is also loss in acceleration. Fluctuation in rpm is usually under 1000 between 500 and 700

Hi,first of all I would get the battery and alternater checked to make shore they are bothe performing properly,I know you have replaced the battery but sometimes even new items can be forty,and with the fluctuation it maybe the maff sencer,the best thing is to have a diagnostic don to find the couse.
best of luck,PH.
