I didn't drive the car for a couple weeks- and now it runs beautifully! No errors (ODB) it accelerates back to normal.

I really hope that's the end of the issue, but would love to know what could have happened here.

To refresh, after replacing the MAF, the accelerator would only work up to say 20% of the peddle- then it would putter. I big guess was that not enough fuel was being injected. Car had sat for several months un-driven.... Then I drove about 10km and it had the accereration issue. I left it another 2 weeks, and now she runs fine.

Is it possible the fuel needed time to "settle" or something?
