[mattcarr]

why would my car be running a low idle and trying to stall when the car warms up.car is fine when cold and idle is high like 1000rpms its fine 8/900 is fine to its when it starts dropping under 800rpms its starts vibrating and shaking kinda at stops and parked.it drops to 600rpms and then its bad trying to stall it only the past two months does anyone have this problem and has found the answer

Try cleaning your throttle body and idle air control valve. Use a throttle body cleaner that is cat and sensor safe. Any CELs?

My 03 corolla is starting to do that stall buisness recently. I was already scheduled to do that injector/throttle body cleaning after the front end work was completed. Heavy maintenance seems to begin at 90,000 miles on the corolla. Im going to use the 3m produce.

I think maybe something wrong with the car engine. You can check it soon.
