Well lads, here's an update. My LTFT is back to sky high 34% at idle BUT the STFT are in the normal range when driving at highway speeds. Can I safely assume that I have a vacuum leak based on these symptoms and everything I have done and replaced?
I have ordered replacement vacuum lines and clamps, OEM Toyota parts.
I have not checked for an exhaust leak, yet. I will pull the mid pipe and replace the gasket after I do the vacuum lines.
I also have not checked my fuel pressure. So far we have been through 2 OEM MAFs, one a known good unit from another car that runs well, and one aftermarket MAF. The MAF -!: FT numbers never change between them.
My STFT is high at idle and falls with RPMs
