Hi Scotty, Thank you for all your videos. I totally appreciate your Knowledge and Expertise!!! Here is my question: 92 Toyota Camry 340k miles. Shuts off at Idle, engine vibrates while A/C is on. No Engine Lights displayed on Dashboard. I would appreciate a video answer if possible. My father 85yrs old and I will try to fix the problem is possible, otherwise a mechanic will do.
