Currently have a 2.2E/S with Webers. It runs well and makes good power, having been tuned on the dyno and further dialed in since then, but I have discovered I'm just not a carburetor person. Fuel economy isn't good enough for the size of engine/car, and the emissions bother me—both in terms of the smells in my garage and while driving the car. And yes, we've been totally spoiled by low emissions cars.
What I'm curious about, for anyone who has lived with carbs and MFI: Is MFI noticeably cleaner and/or more efficient than carbs? Or is EFI the way to go? I'm in no hurry on this, but curious for the experiences of others. Yes, Motronic, but I actually like the 2.2 engine. Thanks! (IMG:style_emoticons/default/beerchug.gif) |

(IMG:style_emoticons/default/beerchug.gif) Cross country I got a little better than 25 mpg with the 3.2 and stock efi. Same as my big Ford Escape. One cause of the lower mileage is the increase in speed limit across the different states. At 85 mph you are way past the inflection of the drag curve. But crossing Nebraska, you feel silly not keeping up with the Jeeps. |
