Hey Vampgrrl :wavey:

Haven't talked to you since you bought your Prelude. Don't have time to bs on HAN, either, in the last couple years..... but I noticed this thread and it sounds exactly like the problems I just had on mine a little while ago (now at 165,000 miles)

I had the CEL throw a code 401 and reak of gas about 3 months ago. My mechanic told me that not only the EGR valve should be cleaned, but also all the little lines and hoses running all throughout the engine. He did it all for cheap, and it cured my CEL and gas smell.

After he flushed out my plumbing, he told me to use a bottle of Chevron Techron once every couple of months. That stuff is liquid gold.

I would suggest using nothing but OEM NGK plugs. Yeah, they're about $20.00/plug, but they are worth it.

Double check all your ignition wire connections, and I would take off the distributor and check the cap and rotor. It may need to be cleaned or replaced. That's something I had to do as well.

Good luck with everything!
