What is the desired RPM of Toyota Carolla 2010 1.8 SR-Cruisetonic Auto in idle and drive state?
My vehicle vibrates too much as it goes less than 800rpm when lights are on and is in D state.
thanks for the help in advance.

Rpm fluctuates between 650-900.
Please go for throttle service if you're facing issue.

I did the throttle service, tuning and catalytic converter cleaning but the issue persists. The last thing I would want to go for is engine foundation change. Any other suggestions?

Have you checked fuel pump? do you experience jerks while driving?

No, I didn't check the fuel pump.Yes, there is some missing but it only happen when the car is cold like in the morning. Once it warms up its fine.

Get fuel filter cleaned up. It will cost you like 1500rs, and pour liqui moly injector cleaner in full tank. That's it, you're good to go after that

Sure! I have changed the injectors recently as two of the old ones were leaked. I get it checked and looks like engine foundations are weak so I am getting them replaced.

Check for vacuum leaks
That is the cause prolly

So, the problem is resolved, I changed the gear engine foundation and looks like it was broken and causing all the vibration.

Now I am facing another issue. Initially the issue was the RPM was not stable like when I put the car on D or R the engine was turning off, it's like the car was missing. After inspecting twice I came to know the temperature sensor was causing trouble it was not giving the right temperature to EDU. So, I ended up the changing the temperature sensor.

Now the problem is when the car is cold and I start it after 7 8 hours the RPM is not stable until the engine warms up. It takes around 4 5 minutes for the car to become stable.
Note: I have cleaned the catalytic converter, checked the air sensor, vtech, changed the injectors, coils are fine. So I think I have checked almost everything.

Any suggestions?
