Got in my 4Runner today and started to accelerate and was met with an awful shaking and blinking CEL, ran my code reader on it and got P0304 (cylinder 4 misfire) so I swapped the boot over to another cylinder and got a misfire on it as well. Quick run down to Advanced Auto and picked up another coil boot and everything is running great now!
I planned on getting the Denso brand but they did not have any in stock. This Intermotor brand has good reviews so we will see how it goes.
