I had the CEL on, so I had my friend run the code. It came up P0102 MAF or VAF input voltage low.

So, I replaced the MAF and cleared the CEL...

Everthing went well for 3 days, until I drove it on the freeway. About 10 miles into the trip, the CEL comes back on. After I went home, I had the code run again. Once again, same code P0102 yada, yada, yada!

Now, all of the symptoms are back, rough idle, clunking in uphill acceleration and stalling after a hard decelleration. :fire:

Any Ideas?

Do you use a reusable air filter? ( k&n or the like?)

edit, yes, I see the culprit right there.

Clean the air filter real well, use less oil for thr treatment, and clean the maf sensor.

even though I have never cleaned it other than knocking the bugs out of id during my last oil change? It's only 7k miles old.

Here is a cheap experiment
Clean the maf sensor, install a paper filter ( fram)

run it this way, see if code returns.
