Miss at idle Dealer says MIGHT be #5 injector 1200$!
Well not sure where to go with this. light to moderate miss at idle. Very recently changed plugs and magnacore wires. Was thinking MAF but no CE light so not sure. Took to dealer and they said they THINK it could be the #5 injector. Can not be cleaned and needs to be replaced. 560$ for part and 600 for labor! RUKM?! And cannot be sure that is the issue. Soooooo kind of at a loss on what to do. Know I need a new Air pump as it makes a ton of noise sometimes but looks like that is just for emissions and would not cause miss. So any ideas? Thinking about replacing MAF sensor and maybe just getting another injector (for much much less than dealer) and replacing it myself.
Any help here would be greatly appreciated.

Problem appeared AFTER you put in new spark plugs?
Could be a faulty plug,effect would be similar to dirty injector.
Replace the plug at that cylinder and see what happens,quick and easy test....

If it is the injectors and the p/n # is the same replace the lot at $20 each. I purchased through the below about a month ago.
