if it is a misfire, then that means it is probably the plug or the wire, change those first, if not then yes check the injector.

The thing is your doing the timing belt the water pump is right their with it . it should cost you much more at all besides the cost of the water pump. When doing a timing belt I have a rule that I go by The timing belt/seals =cam , crank , any pulley & tensioner & water pump all get replaced at the same time. I did a t-belt on a Audi A-8 very complex whole front of car has to come off as well, he didnt want to do w-pump & thermostat his thermostat was their as well not even a month later the water pump gave out he had to pay double the price because he didnt want to do it when I had it apart the first time. And make sure mechanic is ase certified . good luck

Testimonial: "thank you so much for the tips to try.... this seems like it will narrow down my problem... will let you know which solution if the fix."
Check with the place that checked the codes for you. Maybe they can test the IG sensor for you. That might help. Otherwise check all the connections relating to the sensor.
