Since November last year my '93 XR2 has been averaging around 28MPG as my daily ride to work.
I've had it in the shop recently for 5th swap and had new tires at the same time. They also replaced the speedometer cable, which was scratching like a rap DJ. My last 3 tanks have been 22MPG, 23 MPG, and 25MPG after the new 5th gear was installed.
About the only real "change" I know that coincides with this is bolting on the hard top early in October (which was about 3 tanks ago due to the shop time).
I'm sure there might be several possible causes for the drop in economy. Can anyone give this tech-challenged old man some things to check before I send her *back* to the shop?
Thanks!
