You may have an air leak after the MAF. check your connections on the air tube.

If you're single, you should date that chick.

I will tell you that when I installed my JLT CAI in the fender I got exactly what you are talking about. I double, triple, quadruple checked and I had no leaks. I moved the MAF around to see if that would help and nothing. Mine actually would die when pulling up to the light.

Now I didn't datalog, but I can tell you that I got a new tune and it went away. Changing a filter is one thing, but moving it in the fender would require a retune in my opinion and experience.

Try unplugging the battery for a little while to reset the computer.

If you didn't do this when you installed the cold air kit, the computer is still adjusted to the stock intake which might be causing your surging problem.

+1 forgot that one too! Should be the first thing you do before anything else... then take a look at my worthless drabble above.

one, check and make sure the screens are still in the MAF they will devolp a surge also. Two, check and see if the Oil from the filter didn't get on the hotwires of the MAF, if so clean with a Q-tip and rubbing achool

Q-tip and rubbing achool

ummm.....NO! never ever touch the mafs with a cotton q tip! Do use aerosal electronics parts cleaner and let it air dry. The cotton will stay on the meter and cause a failure.

I had the same problem with the KB cold air kit. I was told by a tuner that if the maf is moved even a fraction from stock it can cause that problem and requires a retune.
