Assuming you have good spark and injector pulse and a decent squirt into that cylinder I would try to see when the misfire occurs. The loss of 25% of the engine's power output is the equivalent of a horse trying to run on three legs. I have a 2001 Toyota Rav4 and I am getting a misfire code for cylinder 4. This can be accomplished by. your next step would be to do a compression check on all cylinders. If you are a bit into cars, you have probably noticed that there is a difference in sound from different engines. Driving with a misfiring car is not safe.
