What is the best fuel additive to combat ethanol problems?

I'm not trying to start a debate on ethanol fuels VS regular gas but speaking from experience I've noticed recurring problems in my vehicles running ethanol blend gas (10% ) . My toyota 4Runner I owned would not run on ethanol blend, it had to have 100% pure gas to avoid predetonation.

I'm facing a recurring problem of a slight miss in my wifes 2000 Toyota Camry and my 1997 Honda Accord (running a swapped engine on high octane.) When I run high octane race gas in my accord (105 octane, pure gas) it fixes the problem almost instantly for about 1000 miles. I obviously can't do this in my wifes Camry.

Everyone claims sea foam is the best to combat this problem but i'm seeking further input on the matter. Please, don't bash my statments, I'm going on personal experiences that ethanol blended fuel is bad for older vehicles and just want to figure out a way to "safely" run the blended fuel without having to buy oxygen sensors constantly and keep an eye on my injectors.

How to turn an automatic car to a stick shift?

So I have a 2001 Honda accord and it is an automatic car. My friend has a stick and it is so much more fun to drive. I know there's a way to do this but I heard it can get into the thousands of dollars, I want a cheap way to do it. If there's a way where can it be done. If it is not possible to do cheap how can I make my car sound louder. Please give a lot of info. Also where can I buy a good cheap car.

Car battery stays on even when car is completely shut off?

Had the same problem a year ago, I would completely shut off the car but the ac light would stay on and you were able to turn on the ac. I would have to disconnect the battery every time I shut off the car so it would not discharge. This problem was also accompanied by poor idling at the time, both problems went away on their own but have now come back. This morning I turned on the car and immediately the rpm started going down and the car started shaking, every time I came to a completely stop the rpm went down and the car stalled. The car accelerates fine and stays on while accelerating but I could not reach my destination without having to place the car in Neutral when coming towards a stop and revving the engine to prevent it from stalling. When I finally arrived to my location and shut off the car to my surprise the ac light stayed on and the ac was able to be turned on even with the car being completely shut off. What could be the source of this or these problems and why do they always appear together? I checked the battery, alternator, and starter which all turned out good. I was told I could have an electrical short somewhere but if this is the problem where do I find where the short is? Any info on this problem would be very appreciated.

I recently had to throw out my trunk mat because of smell, any alternatives?

I bought a used car from someone, and the trunk mat smelled like mildew, which made my whole car smell like it.so I threw it out. What is a good alternative to a trunk mat? My car is a 2002 honda accord so they don't make those anymore. I was thinking about buying some heavy material and just cutting out the shape, but I'm not sure which material would be sufficient enough to hold heavy objects like a suitcase. Any suggestions?

1991 Honda accord stalling after left turns, help would be appreciated?

I just purchased a 1991 honda accord besides this problem it's an exceptional condition. Low miles, runs great and awesome gas mileage. I've only had the car for three weeks and only drive intermittently and in short distances. Twice in the three weeks, at night & somewhat colder climates after stopping at a light and swinging a left the car stalled and I pulled over. I noticed the engine light came on and I waited a couple minutes the engine light went off & the car restarted. I unsuccessful tried to start the car a few times and it sounded like the car was out of gas. I was thinking something to do with the fuel supply does anyone else have any suggestions greatly appreciate it cuz I'm at loss here. Recently the car has had a new battery a new distributor a new starter and a new alternator I believe.
