You were due for a tune up at 100,000 miles. Change the spark plugs and spark plug wires. Use iridium spark plugs. They're a little more expensive but they'll go another 100,000 miles no problem. HTH. -Jim

Change the distributor cap and rotor as well. My mistake, you need a tune up every 30,000 miles. HTH. -Jim
