Spark Plug alignment

[Jack's Dodge]

Here is my take on MPGMike's site about getting better efficiency from having the spark plug electrode face injector (or front of the car). It works. Plain and simple. Line them up about 3weeks ago. I have an 88 k-wagon tbi. Mileage sucks and the 3-sp auto is not helping any. So I went for it. Did not index them yet, but I will. Front the start, low end excelleration is more crisp. There is less resistance through the powerband. Best way I can describe it. Gas mileage has noticeably improved. Have not charted the actual numbers, but it is a noticeable gain. I would imagine turbo cars and FFV would see better gains, as I only have one injector.

Hooked up the dist cap mod, so today will be the first test drive

Can you provide a link?

I thought the injectors were at the back of the car? Did you have to shim them?

What Dist cap mod are you referring to? I am extremely interested in increasing mpg. Thanks, Pat

Just finished indexing the plugs...thanks.

if you do the spark plug cap make sure you put a check valve in the line or you could be blowing fuel and air into your distributor cap *BOOM!*

I am going to play devil's advocate here. I want better mpg just as much as the next guy who lives on a tight budget, but I think it is important to stay realistic. When I read about the reported mpg gains mods like the one linked to above, I find myself skeptical. If such a simple and inexpensive mod could produce such a small change, why are the manufacturers using them? And don't tell me that the auto manufacturers are in league with the oil companies to keep mpg lower so you pay more at the pump. The Toyota commercials I've been seeing on the TV lately are heavily pimping the fact that almost all of Toyota's models get at least 30mpg (I don't think they include their trucks). Manufacturers know that fuel economy is an important selling point in today's market with the perceived high fuel prices.

I recall an article in Poplar Science in which various supposed mpg saver devices were tested in a controlled environment, with a dyno, a metered amount of fuel, etc. I couldn't find the article itself, but here is a link to a forum post which contains the results: http://www.mustangforums.com/m_662753/tm.htm. All of the tested devices caused either no gain, or a losss in mpg/and or hp. Has the ozone from the gascap idea (or ozone in general) been tested in a controlled environment? While it doesn't sound like a bad idea at first, when I think about it, it sounds like one is creating a vacuum leak, which would cause the motor to run lean.

I am not goin gto tell you anything about a conspiracy. Maybe it is human error that the mpg of automobiles has altered very little in the past 30+ year.

Perhaps there is a dream world out there were cars are produced with zero issues. They do not need repair, and get superior mpg. Not here where I live. Cars are produced to fail. That is how dealerships get paid. Have you ever seen what some places charge for routine work. My father put out over two thosand dollars for a/c work. Saw a woman pay $375 for a catalytic converter, while I was getting my alignment ($53.95 ). $150 for a tune up. It is unreal. But it is coincidence that engines just happen to be made better in the past. Heck, the tbi engine was not expected to last as long as it did. That is why the odomenter only goes to the 10,000's. Vehicle design has gone down in quality, as dealerships can continue to get paid, after they sell a car that #1 is going to need maintenance and #2 is going to have problems the owner cannot repair. That is just as fact. This discussion has taken place a few times for me:

Let's make note of something else. These fuel saving tips are 90% free. No one is aking you send money anywhere for anything. Put your spark plugs in you vehicle a certail way. Put your comments where your mouth is, and you will find yourself enlightened.
