No power above 4k RPM and bucking does not sound like clutch slip. With clutch slip your car will rev but not accelerate, worse effect in higher gears. Any misfire

Any misfire or other codes? May be cam/crank position sensors, but codes would help narrow the issue down. |

Is the car still revving and not accelerating or is it just bucking down around 4K?. I thought you said the clutch was slipping

revving and not accelerating. but there's a a sudden jolt when it happens. Also now that I installed the new clutch, I think it's sometimes still making contact with the flywheel when the clutch pedal is all way down because it's harder to shift. Could just need some bleeding for that issue though...

Hi, just noticed you mentioned you fitted the clutch yourself.
No idea of your mechanical skill level so please don't take this as any sort of a dig. Could you have possibly fitted the clutch disc the wrong way around. This could possibly explain some of your issues, if it is backwards, the hub of the clutch disc could be riding slightly on the flywheel, which would cause bad engagement & slipping under load.

Couple more ideas for you to consider...
Plugged catalytic converter Knock sensor getting tripped by some sort of vibration and pulling timing Someone put a bad tune in her, verify you have a stock tune Car thinks it's overheating Maybe someone had the heads off and didn't get all the timing right when putting it back together. Bad Gas Water in gas Plugged fuel filter Get a cheap OBDII scanner and see what the engine operating parameters are. Not sure if a cheap one can read the knock sensor so maybe someone on here can recommend a good cheap one for you.

Imo it has be something wrong with the clutch /flywheel if it's revving and not accelerating. But I could be wrong

While DIY is a great way to learn and save money, IMHO, DIY on a clutch (especially since you said this is your first MT car) was probably not the way to go. It's time to bite the bullet and take it to a shop for professional diagnostics. GL.

I torqued it right but yeah I'll bring it to a shop.
Edit: I went to a local reputable shop, NM Imports, and they've done 5 370Z clutch jobs in the last 2 weeks. The mechanic was saying my CSC was probably going out before and now I need a rebleed. They normally tell people to come back after driving a bit to bleed it again. So I'll have them rebleed it since I used a power bleeder last time anyway...

Update: Turned out to be the flywheel as suspected. Thanks for the help!
Here's the old one. I replaced it with the Z1 midweight flywheel. Last edited by Ben370; 02-25-2017 at 07:23 PM. |
