just find it difficult that if you have the coin from a large settlement that your gripping about saving what comes out to literally pennies on gas mileage.

Nice catch! Illinois does require a front plate, so I hope the IHP likes the Army plate on the Beretta. (I think it's great that GM named a car after a 70s detective TV show).

Personally, I think this is the same troll that started the thread about getting jumped in the parking lot while donating used cell phones...

So if you disconnect your spark plug wires on four cylinders, what will happen is you will flood your exhaust with unburned fuel. The fuel will ignite in the exhaust causing combustion in your exhaust. Your exhaust will start glowing red, including the exhaust manifolds and your catalytic converter will melt, and the heat will start damaging wiring that is around your exhaust manifolds.
This is what happens whe just one coil stops firing your spark plugs. Mutiply it time four it should be a real melt down.
Great plan!

Where did you get your numbers because everything I've found isn't even that good! 18city/25hwy is the best I've found for that car. Because of this there is no way, NOOO WAY this is a real post. This whole scenario is much too douchey for me to believe.

If you click on the link in my post, it has : Fuel consumption and mileage: official: 18/29 mpg (U.S.), for the "Beastly" 2.8L Beretta.

Yeah that part really had me rolling too - that is just something you don't label a Beretta, even as it came right off the showroom floor.

The GPZ Beretta's were pretty cool

Got it!!

you have the wrong fuel system on your vette....

(an 01 has no return line).

Maybe someone played a prank on you at the dealer??

Hey OP where do you live in IL. I will be more than happy to come take a look at your car to see why you are getting bad mpg!

If this is not a joke?

I'm being serious! Let me know!

Nice catch!

What does that mean? I didn't buy it from a dealer. I bought it off of someone locally. What's a return line do?

BeastlyC5,

I have been off the forum a while. Today I got back and came across your thread here and find some of the replies worthy of deletion by the moderator. I am sorry you are left to respond to them.

Now to your question, and my thoughts about taking a cylinder or two off line.

Simply Said.....DON'T do it. This is why.

Any vehicle that was engineered to take cylinders off line for fuel economy is controlled with software and sensors to assure a consistent engine block temperature across the entire block. Different cylinders get turned off and on for even block heating. If a cylinder is permanently shut down, that part of the block will remain cooler than the active cylinders around it. This will set you up for permanent damage, either to the engine block, the engine heads, or both. Damage will come in the form of warpage or cracks in the metal with supporting gaskets unable to do their job right and then failing themselves.

Regular every day vehicles will suffer similar damage if a spark plug or ignition to a particular cylinder has failed and left unchecked for an extended period of time.

If you absolutely insist on experimenting, then I advise the following, and I wish you the best of luck with it.

1) The 2 cylinders selected for shut-down should not be in any of the 4 corners of the engine in hope the dead cylinder in-between two active ones would be kept hot enough to reduce the risk of engine or head warping as compared to a corner cylinder which is thermally isolated.
2) The dead cylinders should not be directly across from eachother for the same thermal reasoning. You want "Even" heat distribution.
3) The firing order should be 3 active - 1 inactive in repetition. I have not studied the C5 engine firing order and cannot confirm this is even possible if shutting down 2 of the 4 inner cylinders diagnally.
4) Shutting down a piston should simply involve removing & insulating the connector to the supporting fuel injector, nothing more than that. Do NOT remove the spark plug because some amount of engine oil will spray out and onto the hot manifold near by. This will cause an engine fire. Also, if you don't unplug the injector, you are not saving any gas. It still sprays the same amount of gas into the combustion chamber, doing nothing more than putting a lot of raw gas into your exhaust system, destroying your catalytic convertor and more.

Understand that your engine monitoring system will light up your dash board, indicating engine trouble. If your state requires emissions testing, you will surely have to put things back to original and clear engine codes before testing.

Again, I highly recommend you don't shut down any cylinders, but if you insist on taking a risk, try to follow my advise.

Well wishes....I hope you don't destroy your Corvette.

It allows you to quickly return the car and get a full refund. Look in to it.

This is like watching a train wreck. I know I should look away, just can't

Are you serious?
This has to be the dumbs thing I've ever heard!

I personally don't think this thread should get banned...if anything it's entertaining as hell, but on a more serious note, taking away a few cylinders reminds me of how Mustang Special vehicle Operations team made the Mustang SVO from 84 to 86. It was an attempt to combine v8 power with fuel consumption of a 4 cylinder. Still one of my fav cars.
