Howdy! Great to be here, but on to my problem.
Precursor: Car typically gets 400 mile in total range on full tank of gas
Issue: After I got my tires worked on = car was lifted, a loud rumbling/noise starts coming from the car, sounds like the muffler? The car itself drives fine, revs are still in line with what it should be when idling and at speed. The noise of course gets louder as the revs increase but it is also noticeable when idling. The main problem that worries me is that after I filled up the gas tank afterwards, the maximum range displayed on the dash is at ~330 miles which makes me believe something is wrong with the engine itself even though nothing is out of the ordinary other than the loud rumbling noise.
I haven't gone to get a diagnostic/inspection yet and wanted to see if anybody else has ever hit this type of issue and what it was and if I can handle this on my own. If it would help, I can go film and add a video of what I'm experiencing to better describe.
