my 2000 taco 2.7 4 banger's cyclinder two is missing- threw a P0302 code- what do you think is burnt? Spark plug and wire seem fine??
thanks

How do you know your spark plug and wires look fine? Have you pulled your plugs and looked at them? How many miles are on the wires? Have you check the resistance on the wires?

You need to eliminate the simple stuff before you can go to other items

how do i check resistance on the wire in question? I pulled the spark plug and it looked fine- can i trade coil packs? (switch them?)

I forgot the 2.7 has coil packs - my bad. You will have to search for the FSM on here for your specific year and it will tell you how to check the resistance on the coil packs with an ohm meter.

It will also give you some trouble shooting tips for the code your getting.

just replaced all four spark plugs and installed new blue silicone ngk wires and it runs perfect! the blue wires look good under the hood!
