Running Rich!
I bought a 93 F-150, 5.0L, 4x4 about 5 months ago. After getting better aquaited with the truck, I started to notice a fuel odor. The truck starts up immediately as soon as I turn the key...when I first start the truck in the morning...but if I come out a few hours later, it grinds 4-5 times and then will start, but the odor of gas is present. I have also not been getting as good a gas mileage as when I first got the truck. I have put two Tornados into the air hose and am running a K&N in the air box...Does anybody have any ideas why it is running so rich? Thanx

Did you link the wrong post? That goes to a throttle spacer thread...
First off - you know those tornado things are worthless, right? I'd take em' out if I were you (or atleast don't tell anyone ya got one! lol).
First thing to do is check your computer codes. You can use the search function (link above) and do a search in this particular forum for "computer codes" or "checking computer codes" (or combos of that) and find previous topics about how to do it. Check your KOEO, Continuous Memory (CM), and KOER codes and let us know what, if any, you find.

I'm curious if they help in your truck or not. I have had someone tell me they picked up some fuel economy using a tornado, but that was a TBI engine. I don't know how they work on multipoint port fuel injection. I don't really buy into the claims they make either, but the only test I've seen was a dyno run of an older Honda civic - it lost power.

It's certainly not going to hurt anything - but it's not going to help anything. Just look at the thing - it's so ineffective it's a joke. It's simply a marketing gimic - look at their claims, they are outrageous. It's a prime example of how statistical data can be skewed and misrepresented to their favor. Look up "tornado" on the forums and read what other people are saying about them.

If a tornado type thing worked it would be stock on your truck. Ford execs would sell their mothers, wife, daughters to a cat house if they could get 5 more MPG out of a truck. The best trick to better mpg is to make sure what you've got is working right, at the right pressure and keep your foot out of the throttle. Use the gas pedal like you have no mufflers and the cop behind you really really wants to nail you for noise. Also, if you know you are going to have to stop or slow down, let off the gas early. Don't snort up to the stop and stomp on the binders.

Check the fuel pressure before anything....thats the most common problem. Make sure its around 35psi at idle, and that it holds pressure after turning the truck off....
The tornadoes dont work...you can just google it and see various results showing the facts.

You never remove the positive battery cable without removing the negative cable first.
Remember, your vehicle has a negative ground. That means, that rather than using a postive and negative wire to complete a circuit, it can run just 1 wire to the object and use the metal of the chassis as the returning ground. Your vehicle has electricity running through it at all times when the battery is connected. If you remove the postive battery cable and touch any metal object on the vehicle with it - you're likely to cause a major short circuit which could lead to dangerous problems to you or the vehicle. Batteries can explode!
Always remove the negative terminal first...that way nothing will happen as there would be no connection between pos/neg.
Always work with safety in mind - and please if anyone doesn't know what their doing with a vehicle, get somebody next to ya that can help you.
My uncle was severly burned from a battery explosion/fire. You don't want to get yourself killed or injured by preventable ignorance.
And yes it would be a wise idea to remove the negative battery cable in order to reset the computer.

Anytime.
I suppose I should also point out that you always put the positive cable on first - then the negative cable second - when reconnecting a battery.
Those same principles apply when jumping/boosting a battery too.
