yes run very poorly so i would say misfire is constant
These cars are know for valve issues so the next step would be to do a compression test. You need to compare the compression reading on the number 1 cylinder to the rest of the cylinders. If the compression is low, you will need to have the cylinder head repaired. If you do not have a compression gauge, your local auto parts store may rent or lend you one. If not, they cost around $35.
Perform a compression test and let me know what you find.
