This car again? I think you're the third owner of this car to post on this forum.

Sounds like you should consult with a Porsche specialist in your area.

What did the pre-purchase inspection say about the misfire?

Here are the code meanings;
P1318 Misfire, Cylinder 6
P0410 Secondary Air Injection System - Signal Implausible (Cylinders 1 - 3)
P0303 Misfire, Cylinder 3
P1411 Secondary Air Injection System - Signal Implausible (Cylinders 4 - 6)

Nice colour.

Are the windows tinted?

So how do I fix the air intake codes and I fixed the misfire. And yes the windows are tinted.

The 410 and 1411 are related to the secondary air indiction. Lots of info, but for now I would ignore those two and focus on the others first. It is likely they are unrelated and the SAI is "not critical"...

What's so rare about it?

The Ocean Jade Metallic color. It was only offered in 98-99. Not very many cars painted that way. It's a love or hate color. I found mine in Tucson and flew from SW Okla to pick it up and drive it back. It was worth the effort for me.

Here's an earlier thread about the same car (previous owner).

Although it's a rare color, I don't think it adds 2 cents to the value of the car. I just kinda like it.
