UK Car Repair Questions? Ask a Mechanic for Answers ASAP
Hello. When was the last time the spark plugs were changed?
Have you hooked it up to a scan tool?
I understand your skepticism but you need to understand that we can not touch or see your vehicle and what you are describing falls into a lot of areas that could be wrong.
That being said, a low rpm misfire is most likely in the ignition system and that is the reason for my first questions.
The reason for a scan tool is because toyota is very good about misfire data and that is very helpful in finding out which cylinder or cylinders are misfiring.
Do you know which cylinders are misfiring?
