We,re on our 2nd Vibe(2005) and also currently have a 2005 Corolla.
A few days ago the 2005 corolla with 135,000 miles started misfiring and sputtering and almost dying on the road.
Just like on the internet , my honest , well qualified mobile mechanic pulled the connection on each ignition coil until there was no change in the misfire.
For safety reasons I would advise it,s best to not touch ignition coils, etc. with the motor running.
A new ngk was $92. We put a used one from our old "totaled" Vibe(2003). All is well. Also installed 4 new NGK laser iridium plugs. Applied very little anti seize on the top few threads .
No torque wrench was used. He says he,s got the feel for it.(lol)
