Just came back from Toyota Walton Motors. I told them about problems, The foreman who first inspected the car was saying its normal. I told him that while standing, whenever any electrical component is switched ON, the drop in RPM is logical but during movement it should not be there.
Then the other foreman came and did a road test. He agreed to me and said the RPM should not drop so rapidly and also if it drops below normal then should immediately come to normal position. I told him that it can be due to smaller battery, vacuum pipes, or improper ignition timing. First he said that there are no vacuum pipes in this car. I told him how it can be possible.
Any how he said that throttle body needs to be serviced. Then I told him I want to fix this problem under warranty. Then He called a mechanic, who disconnected the air cleaner pipe from throttle body and then cleaned it with WD40. After that the RPM was shooting to 2K. He said the settings have been reinitialized and it will come to normal after some driving.
Now my questions to expert are:
- Is it possible that the GLi/XLi has no vacuum pipes?
- Is it possible to change ignition timing? The foreman there said that the setting cannot be changed.
- What should be the rating of battery for this car to solve this problem.
regards and thanks,
