hard left turn=engine bog??

[digimanoc]

I was driving my '91 yesterday and there was a situation where I was on a cross street and I needed to make a left turn into a center "lane" to then be in a position to merge into on coming traffic. This is a FAST moving 6 lane road that curves and is blind, so they've made a center lane for you to jump into so you only have to deal with one direction of traffic at a time. Think of the video game "frogger", except with you car and life!

Anyway, I was "jumping into the center" by shooting across traffic and making a hard left , when I saw my opportunity to "merge" into the oncoming cars...so I nailed the gas in second gear while still turning slightly when the engine seemed to quit for a few seconds. It felt like it was out of fuel, like corner induced fuel starvation. I can't believe it was a gas tank/cornering problem from a car the was designed to go around race tracks.

Anyone else ever have this problem? Maybe the TCS doing scary stuff and trying to kill me?

Two questions: Approximately what speed were you going when you hit the throttle and did your TCS light come on?

One more: How long had the car been running that day when that occured?

sounds like TCS...

On mine, when it comes on it seems to prevent me from flooring the gas pedal any more that I want to, as I feel resistance from the gas pedal...

The car had been running for about 30 mins. and I didn't notice any lights.

it wasn't likr that at all....it just cut out for 1-2 seconds and then came back on.

If it only happened once, I would just keep an eye out. If it continues to happen, try to observe any common instances, such as, turning left, TCS or CEL lights.

My gut instinct is this isn't a fuel starvation issue. Maybe coil pack going bad.

I am absolutely positive that it's the TCS... my local track is consisting mostly left turns from 90-100 mph sweepers to a 25-30mph corners.. If there's anything that leads to engine bog due to low fuel, it will show definately... but I had never experienced it in my nsx yet.

the nailed the gas at second gear thing you did could make some very impressive burnt out/ donuts and since it didn't happened with your car, again, TCS is the one to blame (or thank )

I was hoping it wasn't a low fuel thing, thanks.
As far as the TCS was responsible for cutting engine power, it seems a bit severe to totally kill the power for a few seconds. I would've thought it would somehow apply the brakes slightly or something along those lines. It was scary how it just shut off.

 

[apapada]

TCS should not turn the engine off, just turns the power down (as if you lifted your foot off the throttle). I don't think it applies brakes either. If you felt the engine shutting off momentarily (loss of power brakes, light-tree on the dash...) then it is not the TCS and it's definetly something else...

It's got to be the TCS, I wouldn't worry about your car, I bet everything is fine. If you want to make sure, a single acceleration run in a straight line ought to convince you that there's no starvation.

When TCS kicks in it pulls all throttle. If you are expecting (and bracing for) acceleration, when TCS kicks in it feels like you're being pulled forward in your seat, and, when you're not expecting it, it feels like something is terribly wrong. Been there, done that.

The NSX TCS does not utilize any special braking techniques, it just forces a change in the position of the butterfly valve in the throttle body.

that's why I almost always turn off TCS... It's light years away ( backwards ) to those advance body stability system other european cars have... and somehow, it's a good thing

I'd have to agree; when it came out it was a solid, advanced system. However, as time has moved forward, so has the technology around this. It's not a terrible system, but the one time I hoped it would save me (spin in the rain), well, it didn't. :/ JMO, YMMV, of course.

I like to drive at tracks with my TCS, ABS, and every electronic aid turned on. I'm not trying to break track records, just practice being a better pilot by learning lines and pushing the limits a bit at the time. If the e-aid is there, why not use it right ? Track instructors I know pretty well however, always like to tease me by saying that "no amounts of electronics will ever compensate for lack of talent".
