Car is making a backfire/ sputtering. Just started. Only does it when car is accelerating and at high speeds. So only when the gas pedal is pushed down. Checked spark plug wires and plugs all are in good working order. Was wondering if there was a specific thing that causes this on my car. Rather than going through and buying new plugs and wires and injectors and replacing things that might not need replaced.
