MG,
The terminology used on this board is not very complex. FWIW = for what its worth. The letter K after a number indicates 1,000.
As for hesitation at 30mph, you will have forgive us for being slow to respond. Are you asking about putting you foot to the floor at 30mph, or just gently giving it more gas?
At 30mph your car could be in 4th gear and trying to figure out if it needs to down shift to 3rd gear or stay in 4th. Your electronic throttle module (computer based) is supposed to "learn" your driving habits. But it doesn't know that there is a new driver. I have a hard time driving my wife's car because I like to ease the gas pedal down and she floors it. The computer expects me to floor it also, so it doesn't do anything when I ease the pedal down until I hit a certain threshhold - then it goes!
I would suggest, while driving in the city, you drive with the transmission in 3rd gear instead of drive. Putting the car in Drive will not save you any gasoline in stop and go traffic, plus the slightly higher rpm will help your engine oil itself and be easier on the transmission with fewer shifts.
Spark plugs. Your engine has 5 of them, and you neighbor can easily change them for you. I suggest buying them at a dealer or FCPGroton.com (OEM plugs cost about $40) if you want to spend less money.
BTW (by the way) OEM = original equipment manufacturer. Welcome to the board. And it is not required that you respond to every reply to your post.
