According to owners manual should use octane 87 or higher.Don't worry and pump 92 !

It's normal no need to diagnose.Yellow triangle means car is not ready to drive.In this case it came because doors are open and not ready to drive with open doors.And also it blinks and make "beep beep" noise if you drive while parking brake is applied.

When gas pedal is fully pressed, relative throttle position 64.71% throttle position (manifold) 80.78% absolute throttle position B 99.61% accelerator pedal position D 72.55% accelerator pedal position E 89.02%

guys, I have collected following details using torque pro android app when gas pedal is fully released, relative throttle position 0% throttle position (manifold) 15.69% absolute throttle position B 47.45% accelerator pedal position D 16.08% accelerator pedal position E 31.76% Are there any abnormal conditions?

Thanks lot friends.I will have a look at MAF,TPS,IACV .

thanks for your detailed info. I wasn't there at the time of tune up.So I don't know how did they do it.If the problem is with TPS or IACV kindly tell me what should I have to do.

I did all the thing at Wheel Masters at A/pura.The problem with the idle rpm was settled to 800-950 range at working temperature.But the second problem is still hating me.

Hi experts, I have 2008 corolla 141 (not axio 141).I got an full engine tuneup 2 months ago. After that there was 2 problems.idle rpm was about 1500-2000 range for few days now it is settled.Next problem, when I release the gas pedal after accelerate ,engine come to the idle for about 2 seconds then engine raise upto 1500-1600rpm. If i shift to N at that time rpm come to 1000-1200 range.Then I returned to the garage and they did throttle calibration , zero point calibration and lot of things using scanners and techstream software for 5-6 hours.After that car was fine but sadly I was able to drive about 4Kms the second problem came again.
