If you got more than 70,000 miles do a tune-up with OEM type plugs and wires. Stay away from the +4 or Splitfire type plugs, all you need is stock plugs.
Clear codes and see if they come back.

I don't get it why people always expect a old vehicle that breaks down to always be covered under some warranty? If your exhaust tip is larger than your cylinder bore, then you are a Ricer.
