Have Toyota Questions? Ask a Mechanic for Answers ASAP
Thank you for allowing me to help you with this concern today and am sorry to hear that this is happening. i will have to ask you some question to get a better idea as to what may be going on and that we can get this resolved.
I see that you changed the plugs already. Was this condition happening before the tune up? What brand plugs did you install?
Is the check engine light on? Are there any codes stored in the computer?
Thanks in advance and I look forward to helping you.
