I have been beaten by my car throwing P0170 and 173. I replaced the MAF and after that swapped with a known good one to test. It is not the MAF. I ditched my K&N airfilter for a new stocker in case the MAF was getting fouled.

I have searched for vacuum leaks and found no split or leaking hoses.

I can clear the codes and drive around for days with no problems.

I drive to work, take a right into the driveway while decelerating ~20mph and BAM! it throws the code.

I reset the code, drive home and then back to work. I turn the same corner and get the light and same codes again. This is the third time at the exact spot.

The first time it happend, I had the window open and thought I heard a little pop, then the RPM changed.

What the heck!

So these codes may not be the MAF, rather a mixture problem? Would fuel sloshing in the tank cause these errors?

Any ideas on what to look for next?

Thanks,
Ed
