Hay yall,
if you are tired fo poor gas miledge and high gas prices I can help you out.
This works on most cars.
on most cars you can increase your gas miledge for about 25 cents. I took my 1992 chevy cavlier RS from 35 mpg to 40 mpg. with a resistor. yes I said resistor. the air intake temp sensor measures air temp for the engine. well what you do is trick it (the computer). unplug it(the air intake temp sensor) only if the mass air flow sensor and the air intake temp sensor is two diffrent sensors. and plug up a resistor that is colored GREEN BLUE RED GOLD. after you un hook your hot battery cable. it works on most cars so monitor your gas miledge if you have a gas drop undo it. now some cars have a learning computer and it dont work like some ford mustangs it dont work on all cars and if you have any questions poast them here and PLEASE post before you do it. just helping out everyone who has helped me with my questions.
be careful! |

Please be careful when doing this. You are effectively tricking your ECU or "brain" into thinking there is less "air" available so it leans out your mixture, meaning less fuel is being injected to the cylinders. However, there is acutally plenty of air available. When you decrease the amount of fuel in the mix ratio, combustion temperatures can increase exponentially!! This is especially seen in diesel engines! You can damage valves, exhaust systems, catalytic converters and even start under-vehicle fires! Of course there is always room for improvement with a stock engine whether you are increasing horsepower or increasing mileage. However, nothing is free. If you gain something on one side, you have to give up something on another. It may be best to use a variable resistor to find the sweet spot for optimum performance vs. reliability in this case. Very good tip, just please be careful when attempting. It is better to pay a few hundred dollars more for gas in a year than it is to replace your engine or even your whole vehicle if something catches fire.

what this does is trick the computer that the air temp is the perfect for combustion. it does not think it is less air. if it done this it could cause precombustion. example:like on cold days the intake air temp sensor tells the computer to add a small ammount of extra gas to compensate for the cold air. all the sensor is is a resistor that changes resistance accordingly with the air temp not air flow that is the air flow sensor. and there is a device that uses a pot. so you can find the sweet spot if you would like i can retrive the plans and post them for every one. |

A Cavalier is EPA rated at 30 mpg highway and you are getting 35......and with the resistor mod the 40 mpg?
Something just doesn't add up. The "2 guys Garage" car show checked this "mod" and other snake oil mods out last year and they concluded that it was baloney.

i am just telling yall what i done and hope it will help every one out. it is up to you to try it and see if it works and you can make that judgement call for your self. besides if it dont work you only have lost 99 cents and you gain some resistors |
