Hey everyone MY First Post !@ @

I have a standard 150,000km 4 Cylinder Engine 132hp 2000 Dodge NEON !
(best car in the world!) Its Red too@

Anyways I hate paying for gas so, while I was bored messing with my car I just happen to unplug my cars Number 2 cylinder fuel injector just to see what happens, and it started running a little ruff on one end, so I unplug the number 4 cylinder fuel injector to even it out, it ran ruff and die when I tried driving it LOL. I idle it for about 1 minute and then the engine started running smoother and smoother, so I got into it again and the f-ing thing moved! So I said sweet! and backed out of my driveway and began driving on 2 cylinders, ran not that bad, it did feel alittle rougher then normal. I started up the street got to 10km then 20km, then all the way up 60km with no problems, only 25% throttle and got there pretty fast, 70km acceleration slowed. 80km was the highest and couldn't pass it, I didn't want to push the gas pedal to much. so I thought not bad! then I had to go see my girlfriend, plug everything back together and thats it, I was just wonder...

Is it bad to run on 2 cylinders?
Do you think my car gets better fuel economy?

Because it wouldn't be hard to make a switch to shut down 2 cylinders for city and to start them up for highway or 60km+?
