My 91 XJ has 70K on the motor, and runs great, other than a pretty good shudder when it first lights on starting. Idles well, plenty of power.
This is the first fuel injected vehicle I've owned, so other than the typical tune up stuff, what are some leading causes of bad MPG?
The motor was replaced at 130K- for all I know the O2 sensor, etc was re-used
on the new motor. I *did* read somewhere that there is an air sensor before the throttle body which can benefit from being cleaned.
My 87 Grand Wag with 150K mile 360 gets better MPG than the XJ, and that's just wrong!
Thanks
