apologies if were going over old ground here.
heres the symptoms
the car starts fine but driving it for the first mile is really bad - it hiccups badly and your passengers even know it
2nd 3rd 4th all the same. once warmed it seems fine although i feel the problem may still be there but very slightly
its been to dealer and theres no codes whatsoever - they are leaning towards spark plugs.
so is it possible for a bad plug not to throw a code??
they also say there is no update software available but refrained to tell me what version im on
any advice appreciated
