Lastnight I made a WOT run and it felt like the car hit a dead spot. So today I went out and made another WOT run and confirmed with my Scanmaster that the car is hesitating for a second at 4400 - 4500 RPM in 3rd gear. The car pulls strong up to that point and after it gets past that hesitation point. Any ideas on what could be causing this? The car is a 95 Z, A4 and 3.23's. Let me know if any other Scanmaster readings are needed. Thanks.

 

if it happens at just that one paticular rpm it may be a flat spot in your tps

 

If it were a flat spot like you said, then wouldn't it happen in every gear? The hesitation I explained only occurs in 3rd. Thanks.

 

maybe its there in first and second but you just dont realize it...does it do it in 4th?

 

my car did this when my opti was going out it would bog at about 2500 rpms then pull like hell all the way to 5500.
