Q: Regularly maintenanced car has progressive power loss - 1997 Toyota Supra
My car is in good condition and I keep it regularly maintenanced at the appropriate intervals. Starting a few months ago, there has been a significant loss of power; it doesn’t want to ‘pick up’ in acceleration and once at a higher speed, it doesn’t want to sustain that speed. I have always used 93 octane for this car. Since this started, it has gotten progressively worse. There have not been any warning lights or any other kind of symptoms. What is causing this and what should I do to get my car back to performing well?
