Hi everyone! Our 1999 MY Mk1 Punto Sporting is feeling a little sick. It doesn't seem to have the same "go" as it used to and at idle, it's very lumpy with the RPM gauge occasionally jumping up. At speed, I can hear "rushing" noise which I have previously discounted as road noise, but it seems to be related to the throttle operation, along with a high pitched whining. The whine is not gearbox related and can be best heard just on throttle or when the clutch has been dropped, like when stopping at traffic lights.
It had a service not so long ago (albeit a poor service by a mechanic who we will not be using again), which amounted to an oil change and new spark plugs. I have checked plug tightness and lead connection - they're okay. I have connected a vac meter to check the idle pressure - that's okay, too.
My thoughts are that the timing is off. I don't have the tools or the know-how to check that. Am I on the right lines? Is timing on the Punto of that vintage something that any garage can check, or is it likely to be some arcane procedure that is best entrusted to a FIAT specialist with a computer to plug onto the car?
Any advice? TIA.
