Alright chaps,
S2 is back on the road for this year following a headliner retrim. Although I'm not 100% happy with the retrim job I must admit the car looks a lot more fresh inside now. Anyhow, I digress!!
The next issue I would like to iron out, if it is a genuine problem, is to get to the bottom of why my car feels kind of lumpy on the slightest off throttle openings, round the town where the car is moving in say 1st or 2nd between 1-3k it kind of surges or pulses, a real lumpy feeling and is most annoying. It's as is if it only likes going on boost everywhere which is perfectly smooth, vacuum driving not so nice!
Now as you can imagine almost everything has been replaced on this car-
MAF & MAF PINS
N75
DV
KNOCK SENSORS
TFSI COIL PACK CONVERSION
PLUGS
INJECTORS
TPS setup 0.3v - 4.7v
FUEL PUMP
LAMBDA
Idles pretty good, there is a slight stumble but not sure if this is to do with the single mass flywheel. Also no boost or vacuum leaks and no codes.
When I drive on a steady throttle in 1st or 2nd say at 2000rpm as an example, the AFR gauge fluctuates between 14 - 14.7, this corresponds to the lumpy feeling that can be felt.
Is this how all 3B's drives or can you suggest something to look at that I may have missed.
Surely they didn't come from factory like this.
As always any help much appreciated.
Cheers
Gordon
