Cobra Hesitates Under Heavy Acceleration

[Steve1578]

Just as title states, car hesitates under heavy/quick acceleration. What I mean is, if I slam on the throttle, she'll hesitate, almost "stall" a bit, and then go. If I just ease into full throttle, it accelerates fine. I just got a set of NKG plugs and am hoping that solves the problem, but was wondering what else I should look at for this issue.

When was the last time the fuel filter was changed?

Not too sure, just purchased the car last fall, but also on my plans to replace, sorry I did not mention that. I'm replacing fuel filter, oil & plugs, and air filter.

It probably just needs a good tune up.

Fuel filter or the throttle position sensor. I had a skip and it was a combination of those two

Thanks guys!

Don't want to sound like I'm patronizing here but does it still do this when you turn the traction control off?

Yes it does, first thing I thought when it happened, felt exactly like it cut power due to spin, but TC was off. Tried it again doing highway speeds, downshifted, rev matched, then slammed on it and it hesitated for a good second. Gonna get it tuned up and do the normal maintenance, hopefully that cures it.

Just checking... Mine was doing it for a bit when I pulled it out of winter storage. Once i ran through the gas and stabilizer that was in the tank and put some fresh fuel in, it was good.

Could be a factor as well! The car runs fine otherwise, starts good, idles fine, thinking some simple maintenance should clear it up.
Would really like to get on a dyno and have a proper tune. I have heard from countless people that the 01's come with a terrible tune.

Fuel filter or fuel pump. I had the exact same problem.

Thanks for the feedback. Hopefully the fuel filter takes care of the issue!
