Troubleshooting a P0202/P0302 error

[dorqus]

I don't have tons of free time unfortunately to work on the car - the replacement injector was $20 shipped, if it doesn't work, I'll return it if RockAuto will take it - going to try and do the "screwdriver" method to listen to it before it comes. I'll take the valve cover off if I replace the injector and it doesn't resolve the issue... Trying to not do more than I have to in deference of time.

So all's well that ends well.
Got the Bosch injector on Friday, replaced it this morning. No more P0202/P0302 codes and the car is now drivable again!
Took about an hour to an hour and 15 minutes to replace it, not terrible. If I had to do it again it would probably take less time. When I pulled the fuel rail up the upper o-ring got stuck in the fuel rail, so I had to pull it up a bit higher to get a small screwdriver up there to pull out the o-ring. I did put a little bit of oil on the o-rings (upper and lower) when I replaced it to help it go in smoother.

Thanks for all the help!

really helped me see exactly what do to and how to remove the fuel injector clips, it's not obvious when looking at them!
