Acceleration Jerky

[LowRyda2128]

Hi I have VT commodore sedan, and lately its had some strange symptoms that I was hoping someone could help me diagnose.

When travelling at above 70kms and accelerating the response is jerking any missing as such. I dont notice and problems at suburban commuting speeds unless I really put my foot down. Can anyone lean me towards a possible cause of this issue?

Thanks in advance

sounds like you need a good tune and check things like plugs , leads etc

In my VX after a set amount of klms the plugs start failing and missing, different to any other car ive owned same simptoms that you describe, whack in a new set of plugs may be pleasantly surprised, and always a good thing anyway.

my VX did that, mechanic slightly bumped the spark plug lead.. and it was only running on 5 cylinders.. just clicked it back in and presto, back to normal..
