I have a 2001 TT 1.8 that just hit 100,000 miles. Great car! Here's the problem. In 4th and 5th gear around 3500 RPM or when I put my foot into it, the turbo doesn't spoil. Instead it feels [jerky,sputters, hesitant]. Unlike 1st-2nd-3rd, where the turbo throws you back, 4th and 5th do nothing. I found that when its a little cooler outside the car doesn't do the sputter thing [could be coincidental], but still the turbo doesn't kick in. I've heard all types of things from changing the MAF, the DV, the FPR. However I haven't got a straight answer from anyone.

This is what I have done so far:
-new K&N air filter
-new NGK spark plugs
-new Ignition coils
-oil and filter change
-disconnected the MAF sensor to see if that was the problem [no result]


any suggestions would be greatly appreciated. Thanks!!

Are you 100 precent sure you new spark plugs are gapped correctly?
