Hi Scotty, i have an audi A4 2005 which i love driving so much until just yesterday i realised it hesitate when i stop and starts moving again and while its in motion it hesitate a bit and continues to drive like nothing happened. .....what is really wrong with it .

it's a 12 year old audi, endless money pits. But do tune it up with new plugs and filters and pray

Thanks Scotty, do you also think the MAF sensor has something to do with the setuation also?
