So, our cars (as well as most every car made today), actually cut fuel from the injectors completely under deceleration... You can still coast down the hill with your foot off the gas, and still not waste any gas, in fact, you are probably using more fuel by putting it in neutral. When in gear and coasting down the hill, the inertia of the car keeps the engine spinning, even though it is not adding fuel to the engine. When you pull it out of gear to coast, now, the computer has to add fuel to keep the engine running...
Sitting at a stop light, well, hard to say whether it is helping fuel mileage or not... perhaps I'll datalog some stops and see how much fuel is used either way over a certain period of time...
it s not hurting the transmission at all either way...

The engine is not under any more stress while in drive and at a stop than it is in neutral. Perhaps a little more as far as the transmission is concerned, but nothing it wasn't designed to handle.
Removing excess weight is a definite way to save some fuel, but I highly doubt 50 lbs would be enough to be noticeable...

I know this is a Lexus thread but thought it wouldn't hurt to ask. My beater daily driver just died recently. Its a 96 Camry coupe I4. Bascialy I ran the engine with no oil, I know I know. And now it needs a new engine. Its in the shop now and was quoted $2300k parts and labor. The car is only worth 2-3k running.
I need advice on whether to fix it or not? I don't plan on selling it ever, and its my 1st car since I was 18 bought new. So there are some sentimental value to me. 2 door Camrys are rare, about 5000 produced . Its either fix, or sell to the scrapyard for $250.
I don't really need a second car as I hardly drive my IS350. I gotta make a decision by tomorrow. Thoughts, suggestions? Thanks.

Just my opinion, of course...

Here ya go... someone with a Sienna had a similar / same problem - he was pretty thorough, and accurate as well... The Evap systems should be the same between your car and the Sienna - though the parts may be in different places, they still work the same....

I have a 2000 GS400 sometimes on a really hot day if i'm drivng really slow especially on an incline the car just stall but it turns back on without issues. What could be the cause of this? Bad fuel pump, voltage drop or maybe not enough ground? Thanks in advance.

I am inclined to think fuel pump due to it being temperature related, but there could be other causes. We need more info. Do you have to wait to turn the vehicle back on or does it fire right back up? In either case, sounds like it could be very difficult to diagnose over the net. It could even be one of those things that difficult to recreate period.
