Code problems - 98Z

[hotwhip9]

Not trying to jack the thread, but don't want to start a new one..
Mine has thrown an 02 code for a while, on the way to the track it went off, came back on. Had it scanned at autozone, he cleared it, then i drove 75 miles came back on, drove another 30 or so and now its off. 40 miles later still off, but here were the codes:
p0410: malfunction in secondary air system
po174: fuel system for bank 2 to lean
p1415: air pump circuit malfunction
p0327: voltage signal from knock sensor 1 is too low for the current engine operating conditions.
p0171: fuel system for bank 1 to lean

Any suggestions as what to do if it comes back on?

But you did "jack it"......

Not a good idea. Makes the responses very confusing, because no one knows which set of problems are being discussed. Reduces the chances the originator of the thread will get answers.

So.... here's a new thread, all yours.
