What is the Air Screw Best Position w107
Hi all- Thanks for all the help-as I have needed alot. I have 2 questions please (thank you in advance for your help)

:(1. On the front of the engine where the air flow thing is at, there is a dime sized screw. I have been having terrible gas mileage, and someone said that could be a reason. I loosened it and the revs came up, and the car seemed to breath cleaner and better. It that a good way to set that? Or is there a procedure. I noticed on a 5 mile drive the gas consumption did not act as badly as it has been.

:eek:2. I asked earlier about baking in my 107, and someone said to close the heater at the drivers side firewall. It was open and I closed it with a small wire (only temporary-I promise) and wanted to know it that the correct setting for the heater to be shut off?

That is the idle control screw. I can't see how it could have any affect on mileage.

Your D-Jet SL should give you 12-16 mpg, in-town vs highway. That screw is only for idle speed and you should set it to get about 750 rpm at idle. If your mileage is really really bad, check for vacuum leaks...there should be none anywhere. Replace all the vacuum hoses if they are hard or cracked so there are absolutely no vacuum leaks. The D-Jet systems depend on accurate vacuum to operate. Without good vacuum it will really suck the gas.
