My 2007 toyota corrolla s-type has a throttle

Hi it is most likely an air fault, check the air mass sensor and clean it up with carb cleaner, this sometimes fix's the fault so worth a go before buying anything else.

This would cause the fault you mention, Im not sure about the computer issue as I have never had any faults with toyota's ECU's they are normally very good that way.

Is the engine light on? if not then it is most likely to be the air sensor, get back to me if you are unsure.

The mechanic should check on the Idle and adjust the Idle .the car is vibrating because of the Idle is low and the engine can't do to move very easy .there is low fuel coming from the fuel pump going to the engine.The transmission of the car don't have a problem because of you just change the oil . But the Idle has to be adjusted until the car will not vibrate.

99 toyota corrolla hood latch is broken. Can't

There is a rachet right below the hood that you can reach from radiator grill.
Take a long thin screw driver, reach it and turn that rachet.
You will hear the "click" sound and the hood will pop open.

2005 toyota corolla light comes on then goes off for a few days e

Did you have engine trouble codes checked? Parts stores will do it for free. Ask them to explain what the codes mean, and what they recommend. If you have any questions, post them here with the code #'s. The engine light can come on if the gas cap is loose, but after securing, should go off. How is the cars performance? Running ok, just engine light coming on?
