There are many symptoms that an out-of-tune vehicle will have. The first and most obvious will be gas mileage. If your average over 3 or more fill-ups has gone down 15% you are likely in need of a tune-up. Some other problems that may occur frequently are: fast idle when warm, stalling, low power, rough idle, knocking or pinging, hard starting, misfiring, hesitation, black exhaust, engine runs on when key is off (dieseling). If your vehicle is doing any of the above, you could be losing efficiency and performance!
Even if your vehicle does not exhibit any of the above listed problems we recommend a tune-up every 24 months or 24,000 miles. It is a good investment in preventative maintenance which pays off with having a reliable, smooth running vehicle.
