Hi just recently my car has had a rough idle , and sometime when going up in speed theres a slight jumpyness happening, also my exhaust sounds really putty ? anyone know what this could be ?

I would look for a vacumm leak,check the spark plugs, leads also be careful you haven`t picked up a bad patch of juice. maybe fill up with some optimax as my ed use to luv it and go much harder.I am in vic apparently petrol does vary from state to state.

thanks , mmm forgot to say im about 2 months overdue on getting me car serviced , maybe she'll run better once that happens ?

This is such a common problem because there are so many causes.
Concider Vacuum leaks, sparkplugs, leads, dissy cap & rotor, MAP sensor, dirty injectors, dirty ISC solenoid, fuel filter, and dirty fuel.

As you can see a service may very well find what is causing it and fix it.
