I'm going to give it some time before I go further. I think after how crudded up the entire system was my next step will be new O2s (they look original and I'm close to 100k anyway), then I will be looking at the MAF. It seems to track reasonably well, I may work on tuning the MAF curves to see if it stays accurate.
