Yes, last week I switched coils 2 and 3 and cleared the code, and P0302 came back again a couple days later. In other words, misfire stayed on...
Thanks. I don't know how to clean EGR circuit as some things are just beyond me, and I'm running low on patience to do it. But thanks for the...
UPDATE #5 I haven't had to drive much lately but am still looking for the root of my problem. Today I pulled spark plug #2 and inspected it,...
Thank you
Thanks for this. I haven't pulled the injectors yet and would rather not, though I can. By "double dose of Techron" do you mean pour two bottles...

Update: Today I took the following actions: (REMOVED WIPER ASSEMBLY) SWAPPED COIL 2 & 3. BOTH HAD RUST/DUST (SEE PHOTO) CLEARED CODE 0302, 0302P...
Thanks, I was wondering the same. So I'll just add the coolant to the reservoir.
