Burnt out ignition coils

I would go straight to the offending coils with a test light and check power and ground first of all, if those are good your gonna need to get a scope on the control and feedback wires and see what's going on.
Someone did a video awhile back on testing Toyota ignition coils, I'll see if I can find it.

 

If u put the @ symbol before typing someone's name, it'll tag em, also, u can hit quote at the bottom of someone's comment and it’ll reply directly to them.


Do u guys live in mice country? I’d bet dollars to donuts there’s a bad ground somewhere on that bank. Again, I’m just a dummy on the internet haha.

 

Here's a class Paul Danner did on description, operation, and testing of Toyota 4 wire coils.

Scanner dinner is the man. I need to watch more of his stuff.

 

Yes he is a very good teacher, I have learned alot from him.

 

Thanks for all the help, I’ll post up what I did to find the fix.

 

Seems like it would have been covered under emissions or engine warranty. I reserve the right to be wrong.
