Brakes - Fuel-economy :: 1998 Chevrolet Prizm - Loses Acceleration While Driving?
While driving my 1998 Chevy Prizm, my car lost the ability to accelerate but the car never lost power. I managed to pull over and let the car run for a bit before trying to accelerate again..the car only got up to 30 mph and wouldn't go any faster.....after a couple of hours the car run okay. What could be going on? I got new spark plugs, oil change, and an idle air control valve........

I own a '90 Honda Accord and it constantly shakes, has poor acceleration and seems to use too much gas. I thought it was the catalytic converter and I installed a high flow cat. The fuel pump went out so I had that replaced. It shakes less since replacing the cat but I still see the gas gauge go down too low when I press on the gas and the car will stall and stop as I get to "E" when normally I was able to drive many miles past "E". Any guesses? I'm wondering if I need to replace the fuel pressure regulator.

I have a 2002 Subaru Impreza 2.5 RS with about 151,000 miles on it. And it's an auto. I recently took it to about 5.3K rpms on a stretch and it occurred to me that I might be pushing the engine a little too hard. My oil was all fine, and the engine was plenty warm, I had been driving for about 10 minutes but still. I also don't do this too much maybe like 1-2 times/month but I sort of get paranoid about these things.

Every time I turn the car on, the "from start" fuel economy reading resets to 15l/100k. After driving for a while it goes down to 4l/100k but then resets back to 15 once the car is turned off. Is there any way to get it to stay at what it finished at?

While most of the emphasis I've seen on improving fuel economy seems to focus on warming the car up quickly in cool/cold weather, I seem to be experiencing significant mpg drops at the other end of the spectrum.

I have a 2008 prius. Usually it gets me around 52-55mpg, I've had it since January. Since a couple of days ago its not giving me anything above 49. I know thats a normal number, but considering the fact that its usually quite a bit higher I'm wondering what the cause of the drop is. Also around the same time, when I pull out of my driveway I notice what appears to be a bit of water leakage. Its under the vehicle in the front center, and it only happens when I start the car for the day and pull out of my driveway (its on an incline).
View 4 RepliesPrius (Gen 3) Fuel :: How Fast To Accelerate For Maximizing Fuel Economy
I am wondering about how fast to accelerate for maximizing fuel economy. I understand with the P&G approach that you don't want to get up to speed too slowly. The question is whether it really is more efficient to go ahead and get up to speed or stay within the ECO guidelines? In particular, I find that getting up to highway speed especially that it can take quite a while to get up to 70 mph without having it going into the power range. It seems like it is better to get up to speed and then back off to go to the high efficiency mode.

View 3 RepliesPrius (Gen 3) Fuel :: Driving In EV Mode Could Harm Battery?
I've been driving a bit different to try and get some more mpg. I will pulse up to about 45 then let off till ev kicks in and keep the bar right at the verge of going into ice. I can usually cruise at 40 mpg doing this on flat roads while only using the battery. Although if I'm able to do this ev mode for a long distance my battery runs down then the ice kicks in even with the bar below the ice line.
I'm still only getting 50-51 indicated mpg this way but much better than the 42mpg I got just driving it... My route has some hill and my tires are no lrr so I'm think that's has some to do with my low mpg.
Question is does driving 40 mph in ev mode till battery runs dead then recharge with ice just to run battery down again coasting with ev do any harm to the battery?

I have a 2013 Prius V and my mpg averaged about 43. Now after about 13,000 miles it has gone down some to more like 41-42 and even 39. Once on a mostly highway trip it was down to about 34. Last summer it got 51 mpg in Colorado!
How to get better mileage. I once heard about a feathering technique with the accelerator but I don't know if I understand it.

After my electric water pump was replaced under the recall my mileage went from 45 mpg to about 30 mpg. Part of this might be due to new tires and cold snowy weather (CT !) but I have never seen such a drastic drop in performance (2005 Prius).

Our 2010 Prius just had the brake booster recall done and I also installed new pads and rotors. The car now has issues with the front brakes dragging excessively causing lack of power and poor fuel economy. There are no codes and everything else checks out okay, the brakes function fine. Is there anything on these cars that would cause brake drag after a new brake install? I just want to ensure there isn't something I can do before I bring it to the Toyota dealer.

Two weeks ago, I purchased a pre owned/certified 2014 GS 350 F Sport and about a week later my parents purchased a pre owned/certified 2014 GS 350. When driving the GS 350 in normal mode, my parents, my son, and I find the acceleration to be slower than that of my F Sport (also driven in normal mode). When we asked the dealer about the different feel of acceleration, they insist that the acceleration should be the same as the engines are identical. The acceleration in the GS 350 in normal mode feels like acceleration in my F Sport in Eco mode.
