I went and got a oil change now it shaking it wasn't doing it before

Hello, A misfire code does not tell you to replace the spark plugs, or anything else really. It only tells you the conditions during operation. This may be due to the oil cap or dipstick not being reinstalled correctly. Also, it could be the result of collateral damage by a careless employee or even a coincidence. Start by scanning for codes, see what the vehicle is upset about, and post them here if you would like analysis.
