Question Gas mileage? MAF?

Well I almost made it; I'm going into the Air Force in a couple of months so I'm delivering pizza in the meantime and wouldn't you know my little ricer (Toyota Corolla) had to go out on me. Abrupt oil leak ruined engine don't want to talk about it! So i now have to drive my baby (95 Cougar 4.6L) and get it all scrachted up especially with that dang sign on it, it looks horrible on the roof. My own fault, I guess those signs can't handle speeds of 90 mph (pizza in 20 minutes or less right?) and the thing started sliding off my car leaving a streak of scratches down the roof. Anyway to my point; we all know gas mileage stinks for our cars and since I deliver most of the time in the city where it's 35 mph, stoplight, 35 mph, stoplight, and so on. I was wandering if I would save gas by keeping my overdrive off so my car doesn't have to keep downshifting and upshifting. I have a lead foot so I also wanted to ask if I get more power staying in 3rd gear rather than being in 4th all the time. Last question, I know my maf probably does need to be cleaned, but sometimes I can break my tires loose going into 2nd (when my cars warmed up) and other times I can't, when I hit the pedal to the floor at WOT my car launches and occasionally it just goes normal like I did nothing, and at times I can burnout easily other times I don't even get a squeak (traction control turned off of course). I was thinking it could have something to do with the wire connecting my fuel injector and my pedal because it is a little loose, but I don't know if that's how it's supposed to be? Any input would be really helpful THANKS! P.S. I don't know much about cars!

Inbetween 40-50 mph is when the transmission will "hunt" between 3rd and overdrive, keeping the od off should increase mileage and decrease trans wear. Another thing, clean the maf, that should help a lot. You could also do a tune up: spark plugs, plug wires, fuel filter, pcv valve, air filter, o2 sensors, check your tire pressure, check alignment. All these things can adversly effect gas mileage. One more thing, replace the "violin case" intake, and put on a tube. Not only will you get more power, you will see in increase in gas mileage.

Yea clean your MAF... should help improve gas mileage and throttle response.

But yea, you might have a hard time spinning them off the line because the computer automatically retards the timing at shift points and at WOT from a standstill, so prevent wheelspin and jerky shifting. Gotta love the 4.6Ls..

Talking Best way to get more mpg....

...is to keep your right foot light!

Your car will love you back if you don't romp on it between EACH stoplight!!! It's really unnecessary.

Yeah... I drive like that... It's not fun unless you do.
Anyhoo, do like Whitebird said but also, if you so desire, change out the exhaust system. A better flowing intake and exhaust will help your mileage. I went from 17mpg to 19mpg just around town with a better intake and exhaust. On the highway I've gotten as good as 24mpg (hella cool when that happens).

at least SOMEONE SAID IT! I mean dude, you delivering pizzas, why beat the car for your job at your expense? I get on it too when im cruising around... but when you really think about it, all your doing is wasting gas and setting yourself up for tickets... take care of your investment...
