How can I tell if my car needs a tune up?

Check your engine oil level. If it's low, you may need to have the engine checked for signs of wear and tear or replace the oil filter. 2 Look at your engine coolant temperature gauge. If it is higher than normal, this could indicate that your engine is not running properly due to an issue with the cooling system. 3 Listen for any unusual noises coming from the engine. These could be indicators of worn parts or other issues. 4 Pull out the spark plug wires and inspect them for cracks or damage. 5 Take your car for a test drive and listen for any strange sounds or vibrations. 6 Have a qualified mechanic check over your vehicle and make sure everything is in working order.
