I got the code for cylinder misfire on #2. Mine is a 4cyl. I figure its either the coil or the injector. The plug only has 8k miles on it. The 4runner has 208,000. I swapped the coil from number 1 cylinder to #2 and cleared the codes. No check engine light for a week, but it still idled a little rough. Now the light is back on with the same code, so I don't think it is coil related.
I put some of the good $8 injector cleaner in it, but it didn't make much difference. I'm thinking its the injector. Anything else I should try?
