01 Tacoma 2.7 Liter Ignition Coil Failure Rate

I've never heard of a Tacoma having a coil failure rate that high.
I have found there to be a much higher failure rate with off brand coils, for this reason I only buy Toyota OEM coils.
A little more expensive but worth the price.
Also I've found coils to fail if you have a bad ground or power connections.
Use a multi meter to check the ground and power harness for loose connectors and/or broken wires.
Check the ground point for a clean dry corrosion free connection.
I have had coils fail in less than 2 hours due to bad wiring/connections, it caused the coil to internally arc and overheat due to a short in the harness
