I think i found a way 2 save on gas?

Question

i have a crown vic thats is a 8 cylinder car. if i take off 4 spark lugs i'll save gas and not have car problems right?

Answer 1

No, it will use more till it dies.

If it has carburettors, then unless you blank off the manifold (header) leading to those cylinders, the fuel air mixture will be sucked through but nt burnt so it will pop and bang in the exhaust.  If it is fuel injected then unless you do something to stop those injectors spraying it will be the same thing.

Of course with only half the cylinders firing the engine will shake like it is an old heap which it will become very quickly.

Answer 2

No way.....hate to break it to ya, CE and the other posts are correct, your still having fuel being dumped into the compression chamber by the fuel injectors(or carb depending on what year)being unburned and processed out the exaust ,so your kissing 4 bucks a gallon right out the tail pipe litterally.Also you will have one rough idle,due to the firing order in the engine.

Answer 3

disconnect the sprk plug is not bad ....but do not remove them from the hole.

Answer 4

The Mother Earth News had an article about converting an 8 to a 6 or a 4  way back.  I did it on a Dodge van and it worked!  You had to pull the heads, remove the exhaust valve and use a bolt to seal the valve guide. That made the dead cylinders open to the exhaust manifold.  Then you had to go into the lifter valley and remove the intake pushrods and rocker arms for the cylinders you were gonna disconnect.  You wired the lifters up a little so they kept oil pressure in the galleries and sealed the oil holes in the rocker assemblies so you kept oil pressure in the engine.  

This worked best with Big Bore V-8 engines like 455, 429, 460 cubil engines so that you had effectively 227, 215,230 inch engines...my small block dodge only worked because it had a 4.10 rear end and took little torque to move it down the road.  It worked best loafing down the road at 45 to 55 mph!

It was so cool hearing that nasty old V-8 purrring along sounding like a 4 banger!  

I messed up with the 6cyl conversion by disconnecting two adjacent cylinders so that it fired on six, skipped two, and hit six again.  It ran ok until you opened the throttle and asked for power, then it almost shook the vehicle apart...But the 4cyl worked.  Ultimately my wife got fed up with my tinkering on her van and demanded I put it back as it was ORGINALLY!

Did it save gas?YES but mostly because I didn't have the ability to fly down the road.  It saved only about 10%, not much when you consider how much it cost in power.  Its is the cross sectional area of the vehicle and its weight that makes a vehicle economical, not the engine size.

Answer 5

Unfortunately, wrong. Even with the spark plugs out, fuel from the carborator (or injectors) would be pushed into the combustion chamber. But rather than burning (and ulitmately pushing on the pistons), the fuel vapor would be expelled with the exhaust.  

What you would have is a less powerful vehicle that uses the same amount of fuel.

Sorry to break it to ya...

Answer 6

You'll have car problems. The only right way to do that is to buy an engine with variable displacement technology

Answer 7

This is a joke right??? No you will not save on gas, your 4 pistons will be carrying the dead wait of the rotating assembly that isn't firing. Plus your car has a set firing order. If you disturb that it will run rough if even at all.

Answer 8

are you serious? MAUAAHAHA HAHA HA HHAHHA AHHAHAH AHAHA AH AHAH AH HAA

Answer 9

Only if you connect the extra spark plug wires to your skull.
