Hey guys, I've noticed a weird problem with my idleing on my Toyota Truck. After it has warmed up, and it's in neatural, it starts to rev, then sort of die, then rev back up, and then sort of die, then rev back up.
It doesn't seem to affect accelleration or overall performance but it is annoying snd I'd like to diagnose it and fix it before something does happen. Someone suggested that it might be a sensor somewhere.
