In 13K miles I have killed the engine at least 100 times . . . - Toyota Yaris Forums

I have around 4000, to 4500 miles on it at the moment.

Agreed. Killing the engine now and then happens. Nobody is perfect. But a half second or quarter second delay of the throttle is simply not acceptable in my book. For years and years a simple direct connect throttle setup gave us instant throttle response. Now we have computerized "throttle by wire" and it's less responsive? It seems backward to me.

I plan to keep an eye out for a software modification.

I've got 70,000km and I no longer have any issue with the clutch take-up. It was an annoyance when the car was new, but now it isn't. It could be that my left foot has somehow managed to be proactive and fixed the problem without getting my brain involved, or the engine has loosen up enough to return a decent amount of initial torque while the clutch has worn-out enough so that that initial bite isn't as drastic. Probably a combination of all the above.

I find that when I'm running with high octane (premium) fuel, I can loaf around at under 1500rpm without a problem. The engine response feels almost as good as my old car that had excellent initial power.

Since response at low rpm has gotten good (with premium fuel) It'd be cool if the engine fuel cutoff worked until 1000 rpm (instead 1200rpm). Perhap 1200rpm is necessary for a newer engine, but once things free-up, I think 1000rpm would be better. The extra 200rpm of rolling along without any gas going to the engine could add-up to huge savings at the pump.

Its like that bc its more fuel efficient. AFAIK thats the primary reason.

I've gotten used to it. The clutch works great once you are comfortable with the engagement and power levels of this lil car. But good luck driving another car. My girlfriends Prelude SH is a bitch to drive now, I'm so used to the throttle lag her car jumps and chirps every green light. Not to mention the difference in shifter engagement...

Don't even ask me about what it's like to switch from the Yaris 5sp LB to my 5.0 Lx Vert Auto...tire smoke abounds...
