Reset the ECU. It has learned to work in the conditions of a vacuum leak(busted vacuum line). From experience in working on my family's 01 v6 explorer sport, 91 bronco, and 2001 f150, the vacuum system is all one connected system. So, a broken vacu line can cause an overall vacuum issue. I don't know like with my jeep there is an ECU purge procedure,but ...

I found the Ford Motor Companies authorized shop manual on E-bay : http://www.ebay.com/itm/2000-Ford-Excursion-F250-F550-Motorhome-Shop-Service-Repair-Manual-CD-Engine-/230957805521?hash=item35c6286fd1&vxp=mtr It's a full 3 manual set but now on CD. I've seen the paper editions being sold at over $300. The disk version I paid less than $35.

The simple fact is, it's all just mathematics. For instance: (Note: I'm just throwing numbers out here, it's the mathematics which are important.) Given: 20 gallon fuel tank If you are using 93 octane fuel, get 20mpg, and it costs $2.40/gallon At 20 gal and 20mpg, that's a total of 400 miles travel distance. 20 gals of fuel at $2.40/gal, would equate to ...

If everything is ok with the car then after driving the car a full 3 warm up cycles the light should go out. If it does not then reading and clearing the code is the only option. If something is actually wrong with it, fix it.

Your best bet is to read, then clear the codes. The code may not be what you think it is from (low fuel). If you clear it and it comes back, you know you have a larger issue. If it clears and doesn't come back, all is well in Whoseville.

In a non-turbo, non- high performance engine, there's a lot more leeway when it comes to low-octane fuel. However, the Prius has a pretty high compression ratio (13:1), so it will be more sensitive to low octane fuel than if it were around 11:1 or even 12:1. But as others have said, the knock sensor would prevent serious problems. Plus knock usually only ...

For a good explanation of RON vs MON for gasoline octane, see Refining Online. Since your vehicle requires Octane Rating 87 (which is probably (RON+MON)/2) or RON 91, and your fuel choices are RON 90 and RON 95, then technically it is most likely that only RON 95 will meet the requirement. Why? If the manufacturer considers RON 91 to be about Octane ...

Drive smoothly. Avoid braking (safety first, don't crash to save fuel ;D ). Braking turns the kinetic energy into heat energy, therefore the fuel you have burnt to propel the vehicle is now being dissipated through the brakes via friction. As mentioned previously, many people put the vehicle in neutral when coasting. This is wrong, a modern engine will ...

Another concern of leaving gasoline in a fuel tank is that it degrades. If left long enough, it will not burn as efficiently (if at all) and will cause many internal issues. Gasoline in a fuel tank should be good for a minimum of six months before you need to start worrying about anything. Given you are driving the car 2-4 times a month for about 100 miles, ...

Your post raises several possible issues that you could eliminate to start with. Firstly if it is still on an incline I suggest you push or tow it to flat ground. It will help rule out fuel starvation and make it easier and safer to work on. Second i would drain the fuel tank and put fresh fuel in it. From there you can try starting it a few times. ...

Imho adding 2 stroke oil will help lubricates the top part of the piston. What i am worried is, how clean the mixture will burn? Because most 4 stroke engine have egr. If it burns much dirtier, u could end up with more soot re-entering your combustion chamber.

Make sure you gapped your plugs and they are proper heat range

If you cannot siphon/extract the old fuel, it is better to dilute the old fuel with fresh fuel to reduce the likelihood of clogging up the fuel filter when you fire it up for the first time.

Typically the fuel injection cut off switch is located under the front passenger seat but on your specific car it appears to be located in the drivers side of the trunk behind an access panel. More vehicle specific information here
