Car lurches forward while stopped

Hello all,

I may be paranoid or not but I have a question to ask. This is the scenario:

I am stopped on a flat piece of road, I do not have the cars brakes applied, I press in the clutch and put it ito first gear and the car seems to move forward slightly. Not much but it moves a little. What is this?

The road probably isn't as flat as you think. If, as you suggest that you supect, your clutch weren't completely disengaged, you would feel the enging pulling the car. You would feel the car accelerate (albeit slowly) and your tach would accomodate the rising speed.

I know what your saying. My car has been doing it latley also. When your stopped, you put the clutch in and when you go to put it in gear you can feel the car jolt a little like the clutch is not all the way in. I'm pretty sure its the throw out bearing starting to go.

Mine does the same thing. It has since it was brand new (7 miles on it). It's only very slightly noticeable. It does it in Reverse too. My Z has done it since I first got it 40K miles ago too. I don't worry about it at all.

I worry much more about my 2nd gear grind that's been happening since 400 miles were on it (12K now).

I have had problems of late with the car being difficult to shift- 4 to 5th grind(synchro maybe) and it is really hard to get the car into reverse.
Discovered that the evo has an adjustable engagement via the clutch pedal.

The idea here is that maybe the clutch doesn't fully disengage.

To adjust the clutch pedal:

Take the lower plastic section off under the steering wheel. There are 2 screws and to bolts for the steel under carrage and it comes right out. After that it gets more interesting. Lay on your back on the floor with your head by the clutch with a flash light and a 10mm wrench. You will see a shaft going through the firewall that moves in when you depress the clutch. there is a bracket with a bolt you loosen and then rotate the shaft (it is threaded) so it moves more into the firewall piece. Do a little and test- maybe 1/2 a turn or so and take it for a drive. The engagement changes a lot just by moving the shaft a little. Once you have it right, tighten the bolt and put the pieces back.

My clutch is much easier now to shift and the problem getting it to get into reverse is gone. Still have 4 gear to 5th grind but it isn't as bad.

You may want to do this after a new clutch because after a few weeks, it will need some adjustment in many cases.

Don't worry, I'm pretty sure it's normal, it's just that even when you press the clutch pedal in to dis-engage the clutch, the transmission input shaft (that's driven by the clutch when it's engaged) may take a second or two to stop spinning. Since it's still spinning a bit when your shifter lever moves the trans into gear, the rotating energy gets absorbed into the drivetrain, hence the slight movement. Hope this helps...

My bike does it WAY worse - you should see the chain jump and the bike jolt when I put it in first gear at a stop light - doesn't matter if I wait a few seconds or not... MH

You should talk to your service department about it.. I had the 4th-5th gear grind.. There is a TSB and are several revised parts (selector Lever and synchro) that can be installed as a warranty item, but only if its a problem, which you claim to have.

BTW, when the selectors in the transmission get damaged, the car becomes difficult to get into gear, or it doesn't get into gear easily because the gate becomes "off".

The adjustment will certainly help the engagement point if your shifting without completely depressing the clutch and that is whats causing the grind.
