Hesitation rolling on throttle around 2,000rpm
Hi everybody. Just got my first wrx Friday. I bought an 09 wrx sedan with 23,000 miles on it. A big change from the 05 chevy 2500hd I traded in for it. I must say I love the car, everything about it, I couldn't be happier with it. Im not sure if theres any mods to it, but i dont think there is, from a dealer with remaining factory warranty, certified, with an additional 2 year bumper to bumper. I'm new to turbo cars and there's a hesitation I'm unsure about it so I wanted to ask. I researched for a couple hours and couldn't find anything like I'm feeling. I don't know if it's normal or something funny. When I'm rolling along around 2,000rpm and rolling on the throttle just cruisin through the gear, not looking for power, as it's slowing gaining speed it has this short power boost, like a 1/2 second to a second, then it goes away for about 1/2 second to a second, then comes back, and so on till it's a little over 3,000. It does it I've felt in maybe every gear but it's most noticeable in 3rd. I'd like to think it's the cars way of saying "come on let's move!" and me sayin "no I don't like speeding tickets". I cleaned the MAF just to see and it didn't change anything. Thank you everyone for the help!
