But the last time I had taken it to the shop they told me I had an engine misfire
Expert:  Brian Barr replied 1 year ago.
Hi you will need to scan the computer and get the codes to know which cylinder is misfiring. If you can't make it to autozone or find someone with a scan tool. Remove spark plug wire each cylinder at a time with rubber gripped pliers of some sort and check for which one DOES NOT make a difference in the engine idle. That is the bad cylinder

Excuse me you don't have wires you have direct ignition I ment disconnect each connect to the coil.
