Car is Lean (white plugs)

SmokeyDP · 05-29-2001, 03:32 PM

I changed my spark plugs yesterday and the tips are white. I have pics, but my webspace isn't working today for some reason so I will try to post them tomorrow. My question is how do I make the car run more rich? Is there a way to adjust it without any special tools?

Buy a fuel pressure regulator. You might try playing w/your timing a bit.
Good Luck

How hard is it to hook up a air/fuel ratio gauge, I was thinking of getting one of those. Any suggestions on which one I should get?

your car isnt running too lean. the tips of the plugs are going to be white. reading plugs got alot harder since the new gas has been out. they have detergents in them and other additives that make them burn cleaner. also, you cant go by the tips. you should look way down into the plug and see how it looks. if you want to see how the motor is running get some race gas, take the car for a run and shut it off as soon as you reach the end of the qtr. dont let it idle.
if you are set on making the car run richer for no reason, then just raise the fuel pressure.
