Yes, 2 suggestions, easiest and pretty easy.

The problem is extremely common, and is often (but not always) caused by
electrical noise originating in the Air Flow Meter, which confuses the
Electronic Control Unit (ECU).

You can "mask it" with the well-known capacitor fix, or you can clean the
AFM with electronic spray cleaner (the Debi fix) and eliminate it.

The Debi fix is really easy, and worked perfectly for me and the others that
have tried it.

Basically, you remove the cover from the AFM, spray electronic cleaner in,
move the wiper carefully a couple of times, let completely dry, and put
cover back on. Then seal cover with electrical tape good and tight. It's as
delicate as a watch inside, so be carefull not to introduce dirt etc.

The hardest part of this job is removing the cover, as it will be siliconed
closed. So, run a utility knife around the edge of the lid to cut through
the silicone seal. Then, using a screwdriver, slowly and carefully, pry the
lid off.

Start with a corner and don't force it - you could break the cover if you
worked too fast. You'll struggle for a while, then the seal will give, and
the thing will essentially peel off.

I am a believer and you will be too.

Cheers!
