Swap the motor. That's your best alternative. The Honda Accord LX came with two engine choices: a 2.3 litre 4 cylinder engine and a 3.0 litre V6 engine. Both are VTEC engines. With as many miles as you have on your Accord, I'm assuming that you have the 4 cylinder engine. You can find a good, low-mileage, tested, Japanese engine for your Accord at cnsmotors.com among other places. I mentioned them because I had a good experience with them on my old Honda Prelude and many others have said nothing but good thing about them as well. They have a two shops that you can go to if you're in So. Cailfornia. Good luck.
