Toyota Repair Problems? Ask a Mechanic for Answers ASAP
It has done it a lot of times, but is just intermittent. I only know about the loss of spark due to the one instance where it would not start for some time. At that point, I disconnect a plug wire and cranked with no spark. Additionally, because the loss of power is so instantaneous and complete, and then just as quickly completely gone, that seemed to match up with a loss of spark rather than fuel.I agree that it is a pain... like all intermittent problems and may be insoluble until a complete failure. But, I thought I'd gamble that someone more Toyota savvy might have run across this before.of course, it may be an unusual problem and the most experienced techs might not have run across it.
Coil is separate. I do have a code reader. Can they be left hooked up while the car is driving?
