So today i went and got an oil change with synthetic oil i have always been using. After leaving the place i noticed my car would now hesitate when accelerating from a stop. Where should i check for the problem? If its the air filter they fiddled with how can i go about checking and fixing it. Could it be a problem that can fix itself as a drive more? Thanks. I also did notice the oil pressure is above 40 and seems a little higher than usual

 

Sounds like a vacuum pipe that's got dislodged during the oil change.
