A/F keeps going lean
This just recently started happening.
As soon as I start the engine, everything seems fine at first. After about 5 seconds, my wideband shows the A/F dropping steadily. As it leans out, idle gets erratic, and I eventually have to use the pedal to keep it running. It leans out past 17 to the point the wideband won't register. I can rev it to about 2K rpm and hold it there. While at 2K, rpms are still erratic, but the A/F keeps jumping between 12 and 16. I checked all vac lines, fuel, injectors, maf, tps, piping, and coouplers. It didn't do this before. And nothing has changed with safc2. Any ideas?
This is on my b14 de-t.
