Hi guys I am periodically having issues when starting the vantage, any comments or help here will be appreciated. The car sometimes fails to fire when I push the starter button, I have to turn the key back to off then on again and then it fires? sometimes it sorta runs ruff for about 3 seconds and then it will stabilize/ not sure if the two issues are related? was wondering if we need to wait for the self check to complete before engaging the starter?

It runs on 95 unleaded only and has 23000KM on it with no problems except this and I say its intermittent, but embarrassing when you wish to get in and go as you know these cars (regrettably) draw attention so hard starting is a no no.

Please help
