Gas Pedal Delay

m4a1mustang · 09-07-2010, 07:20 PM

That's not really what the issue many of us are describing, though. Of course there's going to be a signal delay, but with this, the engine responds, bogs for 2-3 seconds, then surges forward.

What would happen to me is I'd give the car throttle and initially get put back in my seat, only for the car to STOP accelerating, bog for 2-3 seconds, all while lunging me forward because I was bracing for acceleration... then all of a sudden it'd violently take off again. It felt more like fuel starvation or TC/VDC cutting power more than anything else, although there's no evidence to suggest that's the case. That's what it feels like, though.

Bottom line is I solved the problem... I bought a new car. :/

^^sucks you had to give up the car to fix the issue.

For whatever it's worth, I haven't done any performance mods yet. The car is bone stock with this acceleration issue. I'm going to be giving it to Nissan for a couple days this week so they can troubleshoot it. If they can't do anything with it and no one has found a fix on this site by then, I'll press on with new intakes and possibly a tune. If nothing by then, I'll seriously consider going the route the previous poster has just taken.

gotcha, how do you like the 'stang? things beast and a half i hear.

I get what you describe real bad in first gear, even before the vdc would, i assume, kick in, as well as low rpm 2nd and 3rd.

I had intakes, exhaust, and a tune and it didn't make a difference at all.

I love it. It's an amazing car.

Exactly. It is almost completely unresponsive for 2 or so seconds. The thing that I don't get is that it's very intermittent. Sometimes it's just a little unresponsive for that time, other times it almost doesn't do anything at all, then sometimes it's just fine! Hopefully you'll have better luck dealing with them! Please let us know if you do. I've been brushed off.

I was thinking maybe it was some sort of torque management, but there's no way it could be that considering how violently it lays down the power once it decides to go.

Anyways, I don't have to worry about it anymore since I sold the Z. :/

I certainly hope you guys can come to a solution. I know just how annoying (and dangerous) it can be.
