Octavia II VRS - Hestitation between 1500 and 2500 rpm, power down too!

^{Hi folks,}

 

^{has anyone used the Ecotek Power Boost foam, any an Octavia VRS, to try and clean up the intake? If so, what are your opinions on it? Also, where did you apply it? Just downstream of the MAF or elsewhere?}

 

^Cheers!

Having cleaned my intakes out, I wouldn't waste my money on those particular products.

I'm with R8MXX

 

You haven't said what your mileage is but if you've done more than 50,000miles then I'd be getting a borescope into the inlet (via the air temp sensor) and having a look at the valves & airflow splitters.

 

You can buy a 6mm borescope with LEDs for about GBP13 at AliExpress / eBay, etc.

 

You'll need to tie the tumble flaps open (I just use a rubber strap).

Spend your money on a borescope and check.

Don't delay checking as you can eventually get over fuelling which will see your mpg drop quite a bit.
