1995 Ford Thunderbird mileage: 180,000. I bought my T-Bird used with 70,000 miles. The car pings when you get on it hard. It also only gets about 18 mpg overall. I checked over the plugs and put a professional 3-part injector cleaner in it along with a fuel filter. The car is still no better. Also the car in first gear tachs up to 4500 rpm and shifts and drops to 2900 rpm, which seems to cause the pinging. Is this normal? What can I do to achieve good gas mileage with using expensive premium gas to stop the pinging?
