Have Toyota Questions? Ask a Mechanic for Answers ASAP
May I have the actual p-code that led you to replace the coils?
different expert here. There is either a wiring harness issue, bent or loose pin at connector or faulty PCM. I assume since it is not mentioned under things tried, that you assumed it was coil and replaced it without the required testing, which means the coil you replaced was actually good since the issue still exists.
I have uploaded the testing procedure. You need to follow it step for step, omitting nothing in order to find the cause.
