Help...The car is making a wierd noise
 

Today me and my friend took my z for a canyon run. Its a one way road and its very tiny with very tight turns. i never been there so i wanted to take it easy and i did. the noise started comming before we made it to the place tho. the road that we took to get there was the craziest uphill road that i have ever been on. Pretty much it has areas where the uphill is at a 50 degree angle and some that i would think are up to 70-75. The roads are very tiny and two cars cant fit on it at the same time but its not a one way road. so i missed a turned and i was stopped on a 60 degree uphill (my car facing downhill) when a large tow truck comes head on towards me. to my right there was a driveway (very tiny one) so i pulled in so that after he goes up i reverse out. so i reversed and stopped on the uphill again in the same position the car facing downhill. my friend was trying to figure out where to go and he was like reverse the car and take the right. so i used the hand brake method and when i put down the hand break and started gassing it the car started to make a funny noise. so i hit the clutch real fast and put it in neutral. i let the car roll downhill and i made a Uturn and went back. i got to the place that i was supposed to go to and did the canyon run with minor scraping of the 2 front plastic things that we have under the bumper which is ok because they scrape all the time. when i finished the run i stopped and the car was still making that noise. it only does it in neutral. when its in gear and im driving there is no noise. when im stopped and i hold the clutch in there is no noise. but once i let go i start hearing the noise again. this happen one more time 2 months ago but after i let it rest over night the noise went away. what could the noise be comming from?


Another strange thing that happened was. when i was on the hills the car was at 20mph in second gear and once i hit a 70 degree uphill it felt like it was gonna go backwards because it didnt have power to pull the car. unless i floored it and had it above 4.5-55 rpm, but even then it wouldnt handle it. so after the first failure i quickly revved the car and dropped it in first gear. But still i couldnt drive slow. i had to keep it above 4k rpm so the car didnt roll back or give me the traction control light. is this normal?

Sorry I forgot the number one rule. Search is my best friend here lol

But HOLY SH!T 70 degrees?! WHAT?

70 degrees!!! wow!

:iagree: holy smookes

no way you were driving a Z up a 70 deg incline - gravity is NOT your friend....

I'm thinking 40 AT THE MOST. Even extremely high powered engines on nothing but a tire and wheels and a platform wouldn't make it up anything more than 45 degrees.

I mean - in order for you to climb a 45deg incline... if your car is doing X amount of force as far as tire on ground contact w/ a 100% efficency - then you are moving forward with X/ sqrt(2) force... and gravity becomes (Mass of car / sqrt (2)) - so thats a LOT of work being done lol... 70 deg - forget it man hahaha

I think if a car was just parked at that degree, it would flip back and fall.

What's the name of the canyon?

Frankly, I don't think you own a Zed, you're not smart enough! What is this 70 degree angles etc? Do you know what that must look like?

GUYS! No duh! Magnetic black adds +500 stickies and +500 whp. Black FTW!!!

Nick, save the personal attacks for any other forum but this one. He asked a question about noise and gave some details hoping you or someone else might have an idea as to what the cause of the noise would be. Saying, "you're not smart enough", just isn't warranted, nor needed here. I myself don't know what could have caused the noise but am hoping to hear what other "smarter" people than I might have to say.

Woah - no need to bash - lol I just found it funny that he said the angle was 70 deg - lol - I assumed he was exaggerating :p but woah - dont take it literally man... Also interested in this noise - Could you perhaps take a sound clip man?

This srtange thing happened to me when I was at a clear bra instalation place. The parking lot has a down slope. I parked nose in. So the nose was lower than the tail. There was a guard rail and I was afraid to hit it when I went to put it into reverse. So as soon as I did I gave it a lot of gas. I got out fine. A few blocks away in 3rd, it started pulling after I tried to down shift . I tried 3rd and 4th, like it wanted to be in higher gear and go faster than what I was. But I hit some traffic and I couldnt speed up. I tried to down shift but I just wouldnt go into 1st or 2nd with out pulling and making a ugly noise. I made it to a parking lot and turned the car off. Started it and never had that problem again. I freaked out too. I thought the tranny has malfunctioning.
