Where is the ODB plug on my 1988 Legend sedan (automatic transmission) with 189,000 miles?
About two weeks ago the car just started running rough. The gas mileage has dropped to below 15 MPG and it seems to take much longer to warmup. (I'm in the DC area, so the ambient temps have been low.)Also, the "check engine" light has been coming on occasionally. Any ideas?
Thanks in advance,
