Title: Help with my GTI please
Post by: vwvwvGTI on 15 February 2010, 10:50
Hello all I posted this already but still no reply from anyone.

Having serious problems with my MK4 Golf GTI, 2.0i Year 2000 with 100k.


1) car drives great except now if I try to "floor it" when overtaking etc, it seems to loose power and stutters, yet if I accelerate slowly it runs perfect!

the loss of power (engine stuttering) really worries me.

I got myself error code reader and cable, FREE version but yet it does the trick
The codes I recieved back from the GTI are


Quote
16806 - Main Catalyst: Bank 1 : Efficiency Below Threshold
P0422 - 35-00

17834 - EVAP Purge Valve (N80): Open Circuit
P1426 - 35-10

any help or advice would be great !

ALSO!
I noticed a vibration under the pedals, and when I rev it over 20 it sounds like there is a hole in the exhaust, but I looked and couldnt see any, could a hole cause these errors?

Thanks in advance!
