So I did a double test this morning.

Engaged the hand brake and rev'd my engine, The bite point was around 2K rpm before I heard the creaking of the hand brake going. I didn't notice the slipping in first gear. so as far as I'm aware, first gear seems ok but as described below, there just isn't any power.

Also removed the MAF cable and didn't notice any improvement.

Whilst driving this morning I noticed a few more things
-1st gear just has less power in it. I can accelerate but I have to rev much harder - around 4500 to 5000 to get what I used to get at 2500 to 3000
-2nd gear slips mildly at around 4000.
-3rd gear slips from 3500 to 3000. my car also used to handle change into 3rd gear at around 2700 but now when I change at that rpm, the car seems weak.
-4th gear slips again but performs slightly better than 3rd gear in terms of power.
-5th gear - haven't tried it yet
-Reverse seems unaffected. I put my foot down when I was in reverse and I was still getting the same "oomph"


Many thanks for your conitnued help.

Your description seems a bit contradictory my instinct says clutch, but if I were you I would get somebody who is mechanically minded to test drive your car and give you there opinion  :undecided:

that is deffo clutch slip i'm afraid

see the maintenance section about the G60 / VR6 upgrade - cheaper and better than what you got now and will be able to handle any future power increase :afro:

Hi

Ok 1 question comes to mind. Why would I get a clutch issue right after getting components replaced which don't even effect the clutch? I only ask because I would like to understand the issue without getting ripped off by the garage.

Thanks

Ash

could be that your car wasn't getting full power due to dirty old plugs, clogged air filter etc and now it's running right there is enough torque back in the car to provoke clutch slip..

now this is a possibility but i'm in no way saying that this is what your mechanic has done - but i have heard of people thinking the clutch inspection hole was the gearbox oil filler.. putting oil in there will obviously kill your clutch.

Ok assuming it's the clutch,

how much will the V60 cost and how hard is it to replace myself? PS, I live in London, so where can I get one from?

Thanks

Ok many thanks.

1 more tiny question. The reason why I got my shocks changed in the first place was because everytime I went over a speed bump, my front left side suspension would knock the bottom pretty hard. Having replaced the shocks, I'm still getting the same issue. Can it be that the springs have gone and therefore aren't provinding any protection when going over a speed bump at around 15mph?

Thanks once again.

if your springs had gone wouldn't they have seen that when the shocks were replaced?? could be wishbone bushes or arb bushes
I often wonder why people never expect sarcastic comments from me - they're the only reason I speak...

I'm an idiot. I truely am. Went back to the mechaninc over lunch and luckily he had kept the sparks he took out of my car. He told me that the ones he put in had two spark points where as the ones he took out had 3. Could this be an issue as well? Possibly plugs not sparking hot enough?
