Hi Scotty, just one more question on my 201 Toyota Rav4 2.0L Gas AWD suv.
Per your suggestion on my last request, , I checked the seals on the fuel injectors, and re-installed them. and had the oil change, and fuel throttle cleaned by Toyota, and Now my acceleration from Idle is still a little slow and when the car shifts from 1st gear to 2nd gear the engine revs up. Once it is in 3rd gear, it runs fine. Per Toyota, They thing it is something to do with MAS Airflow sensor and Transmission Pressure test, and they want to charge me $1000+ for fixing Mass Airflow sensor and do the transmission pressure test.
Can you recommend as to what I have to do to avoid the transmission issue switching from 1st gear to 2nd gear. .
