Hi my x14xe corsa b is returning really bad fuel economy !! 170 miles to a full tank ! Also my exhaust is jet black which I've been told means it's running rich ! Has anyone had this problem or no how to fix it ???

No mate the light isn't coming on !! I've had a new lambda on and replaced a split vacuum hose and these have made no difference !!!

When was the last time your spark plugs were changed
Have a look at then and see wht there like. If there fudged. Replace them. And its most likely going to be the temp sensor
