Hesitation at WOT
 

I have just noticed my 8 hesitates during WOT at exactly 7500 rpm. I repeated test runs about a dozen times. Each time, I started with a rolling start at 1st gear, then into 2nd with WOT. As soon as it reached 7500 rpm, I felt a definitely "tug". I know the intake port opens at 7250 rpm, but this "tug" feels wrong.

I recalled there's a thread with similar topic. But if I recall correctly, the discussion was concerning loading condition other than WOT. What do you guys think? Any opinion would be greatly appreciated.

BTW. I have 1500 miles on the 8.

WTF is WOT? :D

WOT = Wide Open Throttle

Pedal to the metal :D

Kinda sorta thoughta! Thanks

If it's consistent, have the dealership check it out.

mine suffers the opposite...it seems to push at or around that RPM...

mine too. still havent pinged it yet though.

Mine too...I feel a push as well....feels good

Sounds like I better get the 8 to the dealer. Thanks guys.

I took mine in for a couple of big bucks or tugs whatever you call it......said my engine was fine and mentioned it can happen when it is damp out or the engine is cold. I haven't had the major bucking since but it does run rough if it is not fully warmed up.

Thanks for the input cruzdreamer. When I discover the "tug", I had already traveled 50 miles on the freeway just prior. Although, humidity was high. It was on the verge of rainning. :confused:
