Save yourself time money and headaches and just do a bypass.

 

Here's another one:

Has Toyota ever made a Technical Service Bulletin (TSB) about this issue? It deals with emission, I would figure there would be something said.

 

There is a TSB for SAIP problems on the second gens but I couldn't find one for 1st gens. I looked for all of 12 seconds. Meh.

Same engine, you'd think it'd be same issue? But I suppose possibly different configurations.

 

@Tail83 If I had to guess you used aftermarket component for the repairs. An initially attractive choice, aftermarket parts will end up costing you more in time and money in the long run. These components are more failure prone then the factory parts. It is not uncommon for them to fail a few weeks or months after installation. This is largely due to the poor-quality materials used to make them and it is not unusual to have aftermarket parts warrantied 2, 3 or even 4 times because codes return. If you are still encountering this issue happy to answer any questions you may have.
