Craigslist "bargain"...

Yes that title is somewhat tongue in cheek, but I do have a question that I'm hoping some of you all will have an answer/educated guess for me. There is a '99 boxster with 150K miles, asking price is $3200, and there is an issue with the car, shocker I know. Seller claims that there is a misfire code on one bank of the engine and has included a picture of the code...they are as follows
P0446 - Evaporative Emission Control System Vent Control circuit malfunction
P0300 - Random/Multiple Cylinder Misfire Detected
P0301 - Cylinder 1 Misfire detected
P0302 - Cylinder 2 Misfire detected
P0303 - Cylinder 3 Misfire detected
and lastly pictured
P0341 - Camshaft Position Sensor A (bank 1) - Circuit Ranges Performance

walk away, or run? or is this something that is common or that there is a relatively simple fix for?

If you replace cam position sensor I'll bet all the codes go away.

What dghii said. The part isn't outrageous in cost and if you are handy it's a do it yourself job.

Yes, but that is one of many potential problems that can cause those codes. If you are buying a Porsche with misfires all across bank 1 and an implausible camshaft position indication, do you want to assume that it's the $30-$90 part that can be reached easily?
I have bought a lot of troubled cars. In fact, they rarely interest me if they don't have a few problems. If I was considering this car, I would assume that the most economical repair would involve a replacement short-block and price it accordingly. The problem that you can easily see, usually isn't the only problem or the most serious problem.

I agree to consider worst case when considering your offer. I've found, on the 4 Boxster's I've bought it that all the potential 'bad' problems ended up not being anything serious at all.

I think that folks that are paying for all their repairs just get tired of it and give up.

Once car I bought, a 98 back in 2010 had a top with a bad rear window no power top operation. The PO told me he was quoted just under $3K to resolve the problems and he was done. I found his power top relay to be missing...weird, but installing a used top relay ($60) restored the tops operation. I then sourced a top and frame for $500 shipped.

and I bet you got an awesome deal on that car - priced as the worst case. Certainly the more you know about these cars, the better 'luck' you can have in buying a troubled one. As a first time 986 buyer, there are a lot of potential hazards. Even with one that is presented as trouble free.
