Ok guys, I need help

[SeanMc]

My car will sometimes start on a dime, but other times, it will turn over then immediately just die. No CEL, codes pulled are: 213...sometimes. Run codes once, it pops up, again, 225, but no 213. I've tried a different DIS, and unfortunately, it doesn't work (off an old motor). I'm hoping to buy another one this coming weekend. Any ideas?

Thanks in advance.

*edit: cam sensor and IAB have recently been replaced*

MAybe check and clean your IAC,and MAF.These can get dirty and cuase problems.Be careful with the small wires on the MAF.They're very easy to break.
Good luck!
