Well, I decided to not half arse this and do it properly. I saw this video from FordTechMakuloco who suggested all you have to do is take off the upper intake manifold (on the Ford 3.8 and 4.2), then just clean out the EGR injection ports with a coathanger:https://www.youtube.com/watch?v=08IxhqpuQ3I
I took off my upper intake manifold and to my surprise, there is no individual EGR injection ports as suggested in the video! If I follow the EGR valve, it seems to take the exhaust gas right behind the throttle body.
However, upon further inspection it looks like one of the IMRC bushings for the linkage corresponding to the cylinder 1 bank of valves fell off. Not sure if this got knocked off when I pulled the intake manifold, or if this was the cause of my misfire. I guess I'll have to buy the part, put it all together and find out. It's just strange that the failed IMRC linkage controls the valves on cylinder 1, 2, 3, but my misfire is only on #1.
