    Vibration when starting in first

    Hey guys been noticing something today when I have been driving around sometimes as I start in 1st particularly when I am on a hill I feel a vibration/slight hesitation in the car, as RPM's build this goes away and all is well but I am concerned as to what it may be. Hopefully its driver error or something as I have already dropped 2500 in parts alone on this thing in less than 6 months

    Where do you feel this vibration? Steering wheel, footwell, center of the car floor board etc...

    You say when RPMs build it goes away? Is it just at idle then cause mine occasionally has done that (I call it a hiccup) and I'm gonna change the VANOS seals to fix

    If it's coming from the driveline, like a chattering sound, it has to do with your flywheel and clutch. I've heard that a little chatter in the clutch area on these cars is okay.

    I sometimes feel a little shudder in the the clutch when starting in first. I suspected a warped flywheel initially, but the problem comes and goes, so Im not so sure.

    Vibration is felt through the seat and gear selector and drops off around 2.5-3000 RPM it does come and go so its hard to nail down. Its not the flywheel or clutch as I literally just replaced them. I'm wondering if its related to a driveshaft bearing or something.

    If it were the center support bearing, I would be inclined to think it would vibrate under heavy acceleration in all gears.

    It's not the car you drive, it's how you drive it.
