Hi, thanks for looking at this...
I've just bought a alfa 156 V6 fantastic car but, 2 problems.
The clutch. Feels funny when changing gear, biting point is about half way but finish's at the top and there is vibrations coming through the clutch pedal. It also seems to shudder when changing down gear.
The eccelerator. Doesn't have the responsiveness that you'd expect.. if you quickly stamp your foot on the pedal you'll get nothing, hold it down inch - 2 inch nothing and then about 10 secs later it'll climb. (" I thought the cable was stuck or something, moved the cable about and it was reving well again. but went bad again") when driving down the motorway you hold the eccelerator down and it takes time before it goes... the injector lights on.

Also think this could be another side effect of the problem... when on tick over the revs hold around 1700-2000 and then when you press the brake it goes to about 750 whuch is ok.
BAFFLING ME!!!!! please help. thanks for your time mate. ste.
("oh my mechanics just told me he thinks it's running on 4 cylinders, i think thats ********???")

I think you need to get it to a Specialist and get it plugged into the diagnostics machine.

The injector light is on because there is a fault stored in the ECU's memory, and the easiest way to find the problem is to get the fault codes read.

The car doesn't have a throttle cable by the way, it is fly by wire.

There is a potentiometer on the pedal and an actuator that opens the butterfly in the throttle body, with only an electronic link between the two. ;)

As for the clutch, V6's do bit quite high up due to them being hydraulic and self adjusting. The shudder could be a worn clutch, or more likely a worn or loose engine mount.

Throttle probs could be the connector block behind the glovebox, some have hard wired this to solve similar problems

What sort of mileage has the car done?
Do you know if or when the plugs were changed last?
The clutch or the slave cylinder could be the issue. The clutch is a pita to change.

might be worth getting the car check for a fault code...

I would sort engine running issue first and sort clutch later...

Hi mate thanks for the feedback, the cars done 74k bought it from a repo auction for 500 :). So that means the car would have been lifted onto a flatbed and taken away with no log book, it's lucky i got a key with it.
The car looks mint. But... i have no idea on history. I've taken it to a mechanic but.. it's a friend of my brothers so that means it'll take forever!!!! he's useless :( i just want to drive it!! anyway thank you all for your advice i'm gonna take it to alfa tomorrow. p.s were you from because i dont know what pita is, i'm guessin it means *****.

anyway enjoy your weekend mate, it's good cruesin weather! :)

Well people thanks for all the info but my mechanics a lazy ****. Dont think he has the right machine for fault finding. He's changed the throttle body and that doesn't do anything.
He says there's about 20 codes that come up, the main problem is that the throttle is'nt responsive... Hold it down and it'll work eventually. Move the cable in the engine bay and it works for a bit and then drive it and it and back to the same problem. Think i might end up selling it and buying a better one.
Been a month now that the machanics had it!!!! Think philski's got the right idea with connector blocks. Anyway thanks everyone and happy driving in this sweet weather!

Have you traced the cables back to the connector block?

It may be the throttle potentiometer itself
