My car has 160k on the ticker and my injectors came out easily. Be careful with the injector clips on the wiring harness. The twenty year old plastic likes to break. I sent mine to WitchHunter Performance. It cost me 15 dollars per injector to get them sonic cleaned, new injector seals, and a flow bench sheet showing how each injector flowed before and after cleaning. When you get them back paint the bodies, as they will blast all the stuff off, making them look almost new.
If, when you get them back look at the flow sheet. If any of the injectors is still flowing significantly less than its maximum it might have to be replaced. I only had one that didn't flow at its full potential, but it was only 2cc's lower than it should have been.
