Engine "wobble" when changing gear??

[MattyV6]

Hi all,

 

Bit of a strange one, that has always happened since I've owned my Zed (coming up to 2 years now).

 

When accelerating normally under normal driving conditions, when I change gear sometimes you can hear the engine revs fluctuate and the rev needle itself actually wobbles up and down a bit. Its almost as if you've done a really bad gear change to too high a gear or something, even if you havent. Its hard to explain.

 

However... when driving the car flat out and changing gear, its absolutely fine. I think the rev needle still wobbles a bit for some reason but the engine note doesnt fluctuate, it just pulls hard.

 

The car has had a brand new (Exedy) clutch fitted in the past year and a new LUK DMF as well as I suspected these were the cause. Unfortunately this made no difference! The car is currently on 103,000 miles and I bought her on 80,000.

 

Any idea what this could be? I'd love to get it fixed

Sounds like the MAF or throttle body might need a clean

[MattyV6]

Doh sorry its a hard one to explain! It seems to me like its something transmission wise tho, a mount or bushing perhaps.

 

Engine runs perfectly so don't think it would be that.

 

I may try and get a video up perhaps? If that would help

Take it to a good garage and get them to test drive it. Where are you based?

[MattyV6]

Yeah that might not be a bad idea. I did mention it to my garage before and they thought it could be something to do with the diff. Said they owned a few cars before with similar problems and its more hassle than its worth to fix. They didn't properly look into it tho. I was just wondering if this was something anyone else had experienced with a Zed.

 

I'm based in Devon

Mine does this, I thought I read some cars just do it and everyone had just learnt to live with it.

 

I've never had anyone look at mine so report back if you find a fix

When I change gear my revs jump up a couple of needles without touching the throttle.. I do have a lightened fly. But it did do it a bit with the dual mass

[gareth29]

had something similar but it was because my idling speed was too high - so around town the revs would surge when i declutched - really annoying and it made for very jerky progress - a pedal dance seems to have really improved things

Sounds like you haven't yet mastered the new clutch. double de-clutch on change downs.

[MattyV6]

Oh crap I forgot about this thread... lol

 

I still need to take that video to explain it a bit better. I hope its a fixable thing. I've been living with it since I got the car but it would be much nicer if it was fixed. Not to say she doesn't drive nice I just want her to be perfect

Is that double de-clutch every time you drive the car, or just when you have new clutch?
