2001 Toyota Tundra

I have a 2001 Toyota Tundra V8, cylinder 5 just keeps misfired. I tried everything by replacing the coil and change the spark plugs. Nothing works! Looking for ideas

 

Spark plug wire?

 

Coils

 

I change the spark plugs and the coil

 

How old are the wires?

 

No wires

 

Where the wires are located?

 

I have a '97 T100 3.4 V6 withe 3 coils on one side with spark plug wires connected to coils that run to other 3 spark plugs, you shud have same????

 

Or the wire that connects to that coil

 

Change the wires

 

Were you having the problems?

 

No, but I'm trying to narrow down if it's not coil (new) and plug too, only thing left would be wire, if they old or pinched, cut, frayed or something in that chamber (debris)

 

Are they expensive?

 

@Roman parts guy if you want OEM parts

 

Slim chance, but the new coil could be defective (cheap China one

 

The 2UZ uses individual coils for each cylinder, so the only wires running to it would be from the engine wire harness. You can visually check those out and make sure the connection is good.
