Hi all,

My V8 4.3l roadster has started to take a bit more throttle to set off than normal and is a bit jumpy at slower speeds around town....any ideas?

Cheers!

 

is the weather getting colder? are you letting it warm up? does it go away after a few minutes of driving? how many miles/km are on the clutch?

 

Hi, yeah they are short ish trips but its fully heated in regards to the temp gage. its pretty much happening all the time. it has 13,000km on it.

 

Has it had a battery issue or ECU accessed recently? Wondering if misfire corrections have been a lost. If scanned by an Aston tech they would be able to tell you.

 

Not that i'm aware of, will book it in for a check. cheers

 

Try a clutch relearn procedure it might help.

 

2nd that..but a little more throttle usually means the clutch is finished..a AM tech at the dealer can check your clutch bit count and give you an estimated clutch life usage/remaining..1200bits= new, 1600bits=50%, 1700bits=finished no drive available..there is only 1mm of wear from 1200bits to 1650, once clutch is 50%, drivability issues start to show up and clutch needs to be replaced..hehe this is the reason "launch control" is not talked about in the owners manual, yet all AM cars can do it..just on a Vantage you get 3 launchs, the 4th launch you better have a flatbed phone number ready...from what I've seen, depending on driving area..clutch life usually ranges from 10,000km to 45,000km, 90% of the time 12,000-25,000km..

 

irish there are may that have over 45k kilometers on their clutches....perhaps they have just not come in yet?

 

Could spark plugs be an issue?

 

I have heard of the hub speed sensor failing and causing bad information to be sent to the ECM causing jerkiness.

 

How about a little more basic info to help troubleshoot this.....

Year/mods/mileage? When did this start happening? Were there any changes to the car that corresponded with it including maintenance work being done (oil change, brake fluid, etc)? Is it consistent or only happen sometimes like when the car is warm or cold? Any other information would be helpful too...
