am I running rich???
 

I did a freeway trip mileage check for the first time and got about 16 mi/gal crusing at 70-75 mph and 3000-4000 rpm. Is this about right for a 2.2, S pistons & cylinders, E cam?

I don't really care about the mileage but am wondering if it's running rich.

Thanks in advance,

Rob

Pull some plugs and see what they look like.

Try the DVM to O2S method to get a reading if you don't have a LM1 which is prefered.

If you're running rich, she will want to stall when cold with sever sub-dips in the RPMs.

my 2 cents
