Your injectors our easy to take out, just a little time a patience. You dont need to get new injectors, you can have them rebuilt. The cost to rebuild them over buying new ones will make you very happy. Find a shop in town that will do them for you, it will be cheaper if you took them out and took them to the place.

I know this may sound "dumb" but here goes anyway. What this sounds like is the gap is different on all of your spark plugs.
As good as our computerized engines are, they can't control the timing on an individual cylinder or if half of the spark gaps are worn twice as much as the other half.
I've heard a lot of really ignorant stories over the years and this includes the platinum plug theories but I have turned many a rough idle into a smooth idle just by pulling out plugs that were way out of spec's. Some will have eroded away to quadruple the gap while others are just two to three times as eroded in the same motor. Platinum contacts? Missing in action. Insulators? Pieces missing and God knows where they lodged. Electrode? What electrode? And some end up having to have the head removed and sent to a machine shop to have the remains of a plug removed since it had essentially welded itself in the cylinder head after having been in the motor way too long.
The only other thing that would cause your lean and rich readings is individual cylinder compression. Engines rarely wear evenly on all cylinders and compression in one cylinder may be OK and another so-so and another way below spec's.

it is rare for the injectors to all go bad at once...matter of fact never seen it...you should try running a can of injector cleaner through a full tank of gas. There is most likely some other underlying problem....it's pretty hard to run lean and rich at the same time...you are either one or the other...just can't be both...perhaps the oxygen sensor is faulty...I'd get a second opinion on this.

Because your mechanic said injector tips, they must be a seperate item. You replace them. No different than a paint spray gun tip. They dooo wear out.

You can try cleaning them with a injector cleaner that you put in your gas tank, if it doesnt work, you have to change the injectors.

Definately get a second opinion iy may cost you a little more but will save you in the long run.

Your best bet is to get a second opinion on that.Try an injection system cleaning first. Make sure the EGR valve is clean and functioning properly.

Guys, this is B.S. Unless the mechanic is stupid and doesn't know what he is looking at when the O2 sensor is crosscounting.
