Hey Scotty, long time viewer love what you do. I’ve got a 2022 Toyota Tacoma with about 54,000mi, V6 engine and manual transmission. I recently replaced the spark plugs and found two plugs on the driver side bank had some crusty white residue on them on the cylinder closest to the firewall and the farthest. The middle one looked fine. What could be causing this? The truck would sometimes clatter under load going up hills and after the plug replacement it seems to have improved. What do you think is the root cause?
thanks

Well, white means they're burning a little bit too hot. It could be you've got some kind of weird fuel or one of those injectors wasn't spraying right? If they don't spray right they will run lean lean makes them hot and would make them white. I would run some fuel injection cleaner through it
