Two weeks ago my car started malfunctioning and had to be towed home. It ended up being the MAF, which was replaced 5 months ago.
Car ran extremely well until today, again started malfunctioning and had to towe it home. Before it was taken (I'm still at work) I was able to get these OBDII codes:

P0300: Random/Multiple cylinder misfire detected

P0301: Cylinder 1 misfired

P1296: ???

Any idea what should I start to look for when I get home?

in the mean time, I'm gonna start reading

 

Update: Got home and started getting the codes, got all these: 17887, 16684, 16685, 16688, 16686, 17536, 17704, 17544, 18010, 16804, 17763, 17658, P0300, P0301, P0302, P1296, P0420 & P0351. Decised to clear all those codes and see which ones comes back. While doing all these, the battery died. Waited till these morning, boosted the car to started and now its running like nothing happened. And no codes???
