Hi... I am having this problem too. Not in that particular order though. First, 3 and 4 failed ( i swaped them around and all the other coils were firing except the two that were originally in 3&4) so i bought 2 second hand original lexus coils. When i installed them, instantly, two of the other coils went (5&6). Once again, i canged them all around and all the coils are working including the onces i bought except the two coils that were in the original 5&6 position.
Wana, have you had any luck with the new coils?
Does anyone have any clues? I dont want to keep replacing coils if they are just going to blow.
I spoke to an auto elec and he said to just keep replacing them??? seems odd that all the coils are good and then 4 blow in 3 days.
Please help!
