Replying to: nmarcel1 (Dec 09, 2008 8:24 am) "TSB installed to fix...."   It is entirely possible, even probable, that the TSB hesitation fix involved keeping the ATF line control pressure elevated for a few seconds immediately after an upshift is completed. Just in case a required, re-acceleration, downshift is soon to follow. They may have even added a "virtual" dashpot as used in old carburated engines to prevent the engine from stalling due to otherwise too quickly falling to idle upon full throttle release. In city driving those few extra seconds of high ATF line pressure coupled with DBW being used to more slowly reduce the engine RPM to idle could add up, resulting in lowering your FE overall.   Ford has recently adopted a variable displacement ATF pump to combat this very same problem. High volume at idle so the ATF pressure can be quickly raised even with the engine idling, but low volume at high, higher engine RPMs for improved FE.   It is my belief that this would be just another form of the "fix" for the premature transaxle failures of the '99 & '00 RX300's. for the '01 and up RX300 models they reprogrammed the ECU firmware to constantly maintain the ATF pressure a a high level, result in severely burned ATF in as little as 40,000 miles. Then that development resulted in the need to change the ATF drain and flush maintenance schedule from infiniti, life of the vehicle, to every 15,000 miles.

Replying to: notmybmw (Dec 09, 2008 7:22 am) In layman's terms, if my car is having this problem, can you describe how it would feel and at what speed I would be feeling it? Would I need to do something to make it happen? Also, do you think I am correct that I should be getting better mileage, even with ethanol added to the petrol? Thanks. Ruth

Replying to: 210delray (Dec 09, 2008 7:20 pm) 210delray: respectfully, if you think 15-16 mpg city is acceptable for a 4 cyl it leads me to believe your mileage might be in that same range - I hope not! I would be plenty upset if my '09 I4 auto used that much fuel. Even in-town running the a/c the lowest I have gotten is 24.3 mpg and have gotten as high as 34.7 mpg on a road trip at a constant 70mph.   4ruth: those mpg numbers are unacceptable by any standard. I would continue looking for solutions of which are beyond my expertise. (May be why the car was traded in....just a thought.) Maybe some of the other gurus can weigh in on Post #4661.

Replying to: 4ruth (Dec 08, 2008 7:12 pm) I would first have the dealership check whether the TSB for engine and transmission performance have been applied to this vehicle. When the first one came out early in 07, a TSB directly effected engine performance and also helped with the shifting. That was then superceded over time by two others.   Secondly I would also check tire pressure inflation, I run 2 lbs over the typical pressure....make sure you are on the high side of pressure as opposed to the low side.   Hard to imagine that you would have a dragging parking brake, they normally get looser over time as opposed to tighter, but I guess if someone mis-adjusted it that might add some drag.   I'd be switching fuel stations, to see if that had any effect. I run the cheapest available regular, but have two regular stations I typically hit which I've never had a problem with their fuel in 15 years.

Replying to: atb2 (Dec 10, 2008 6:48 pm) I was responding to nmarcel, not 4ruth. I think 4ruth's gas mileage is too low.   Personally, my 04 Camry 4-cyl 4A ranges from 23 mpg in town to 38 mpg on the highway (speed no more than 65 mph).   My '05 Camry 4-cyl 5A ranges from 20 mpg to about 35 mpg, in other words, 3 mpg less.

Replying to: 4ruth (Dec 08, 2008 7:12 pm) I have now taken the car into both Toyota and to the Honda dealer where I bought it and both are saying that getting 15 in town and 22 on the road using cruise control is acceptable and that nothing is wrong. What do I do now?   I have written the owner of the place I bought it and told him how the salesman looked me in the eye and lied about the mileage and about where the car had come from (he told me he was getting it that afternoon from the first owner who had bought "up" to a larger fancier car and was bringing it in for a trade in. I asked for the car fax but did not actually get it before I had signed most of the papers. Then I saw that it had come from an auction...and was given a song and dance about how that was simply how it had been transported to Portland. I can't believe how damned naive I was.

Replying to: 4ruth (Dec 22, 2008 2:49 pm) Both dealers have more crap than the christmas goose. Go back to the toyota dealer and ask for a print out of all warranty repairs done to the vehicle. They have the ability to give you this. Toyota provides them a web site to check cars for delivery date and such. It also provides what warranty repairs were made and at which toyota dealer. A lot of things can go into poor fuel mileage. One thing I would check is that you have the transmission in the "D" position and not in four. If this is the case and you have been driving in the 4th gear your gas mileage will really suck.(I say this not as an insult, but a point to check). If you would like you can send me an e-mail at dssi1199comcast.net and I will be happy to go over the problem with you.
