I felt the hesitiation, it freaked me out compared to driving my Accord v6 w/drive by wire as the Accord is a lot more responsive in terms of auto gear shifts.

The ECU has to learn your driving style. Also, using premium gas helps as well. Drive w/ a lead foot for about a week and hesitation will mostly be gone.

Many folks have tried to do a ECU reflash update by Toyota, but have reported mixed results.

The only current solution is to use Sport Shift mode, but that kills fuel economy. Honda doe a better job of transmissions on drive by wire, but the Solara is 99% perfect other than DBW jerkiness?

The Flash does help, and no premium gas needed, manual on the solara states to use 87 so regular is fine.

The manual for the Sienna says the same thing about using regular unleaded. Trust me, do a week w/ premium and do a week w/ regular. There is a huge difference. We use the same engine as in the Solara. www.siennaclub.org has over 2 years of info about the hesitation issue and how some folks have tried to solve it. Mine dissappeared after I started using premium gas. Since I already drive w/ a lead foot, the ECU quickly learned my driving style. A flash was supposidly done at my last service (i gave the the TSB on it ) and I"ve noticed better fuel mileage since then.

I don't care what the stupid manual says about what fuel to use because that's manipulated by marketing dweebs who know nothing. With 10.8:1 compression and port injection you should not be putting in anything less than premium fuel in the 3MZ-FE.

3MZ-FE rating on regular: 210hp/220tq
3MZ-FE rating on premium: 223hp/238tq

The engine detunes itself on regular by 18 lb-ft of torque which is a huuuuuge difference. Especially with a minivan where you always have a much higher load, you should not put in anything less than premium. Our Highlander has the 1MZ with 10.5:1 CR and regular vs premium is a pretty big difference there too. But it doesn't have ETC so we don't have any problems with throttle lag either.

I'm a business grad student, point is that I see the clashes between marketing vs. design vs. engineer vs. management/low costs/market penetration. Premium fuel works as a negative strike for a car b/c of the perceived 10 cents/Litre or 20cents gallon difference, which seems to fall under increased operating costs. Definitely, not true.

To be fair, I took all of your advice and put premium, first of all Sunoco 93 (a little insane) but 4more mpg, smoother less herky jerky and maybe even better acceleration due to not being detuned have been noticed. I averaged 29.3mpg doing 65-85mph with occasional squirts to passing gear in a 1.5hr hwy run. This is on a Solara
