Bottom line: you may save few % on the fuel bill, but your engine will have lower power output and higher wear at low rpm due to imbalance. [-> that will cause the ecu to run at wider throttle to prevet stalling]
Want to save $ on petrol? Drive accordingly. [!= slowly]
HAHAHA WRONG by unplugging your injector you just cut out fuel to that cylinder so now your car is running lean. Your O2 sensor will now adjust fuel to the other 3 cylinders to accommodate for the loss of fuel so you will now have 25% more fuel in those 3 cylinders and will actually burn more fuel. ALSO that is NOT cylinder deactivation. DUMB ASS haha
right and wrong it is an O2 sensor and does read how much O2 is in the exhaust gasses. BUT it is programmed in the computer what the amt of O2 in normally combusted gas is. By removing a cylinder it will read it as running lean on fuel and add more gas to the remaining cylinders.
@jayandersons Plus doing this will certainly hurt the engine if done continuously because newer production cars cut out cylinders before the exhaust stroke so that the exhaust gasses remain in the cylinder to act as a cushion for the piston.
The MIL is flashing because you can damage something. It will flash when it is something pretty serious. Plug that injector in and stop fucking around with something that was built that way for a reason. You will damage something in the long run
thats a good way to bend your crankshaft...you will want to get rid of 2 cylinders to be less damaging...but then you will have to crank up your idle to give it enough momentum to carry on the rotation...unfortunatley, your spark plugs are now fouled and your valves are getting gunked up. the oil cycle is still going on in the system. If you were hard core, you would plug it entirley, and remove the pistons, then it might work....but it will barley have enough power to get it moving.
you computer will be giving it more fuel wont it? because its still got the exhaust gas oxygen sensor, that senses how much oxygen is in the exhaust...
because theres going to be more oxygen, as one cylinder is going to be pumping fresh air into the exhaust.. computer will see this and give it more fuel...
WAIT... engine light on means limp-home-mode... it ignores most sensors, my mistake, you may be saving fuel
I dont believe your numbers or a few reasons. 1: your in open loop on the computer which isnt designed for fuel efficicency 2: Without floating the valves like on a production engine you still have the pumping losses so you have the drag of the 1 cyl without the gain.

@P1ayaH8er its a oxgen sencer not a gas sencer , so it wont add more gas

If you run cylinder deactivation at high way is ok, but run the city, fuel consumption will increase.
