Not to get off topic, but as far as this video goes, had the owner followed the recommended change schedule, this wouldn't have happened. 140k miles is way too many for original plugs. These plugs also act as a sensor for the vehicle.
Toyota recommends flushing with the coolant, drain, fill, repeat, and it's 50% diluted from the bottle. That's probably what I'd do with my Mazda. Expensive? Probably, but takes the guess work out.
Lol, those are the exact same ones I use on my Scion's winter wheels. Walmart specials at $32 a set. Can you post a picture of the whole car with those on?
I don't play road tag anymore. If someone gets too close I just pull over at the next available space and let them go. People don't learn the consequences of their actions until it's too late. I try not to be part of their scenario.
Yep, all-seasons are a poor substitute in slippery winter driving conditions. I've caught myself driving on icy back roads in the early dark morning hours for miles without realizing it a few times.
That is exactly why I stay off the highway during bad snowstorms, I take back roads. People who don't have experience in snow do that crap. Especially the influx of new drivers every year.
So, what are you actually experiencing here? "Has lots of play", is this some thing they noticed?
Problem description is vague, I'd get a second opinion. It may somebody's unprofessional opinion.
Doesn't matter how long you wait, you're never going to get it all out. There's always at least a quart left in the engine on and in internal surfaces. My wait is about 10 minutes.
