Well that will get your 4. Providing they are the right ones. Neon used like 4-5 different injectors in the pre-99' engines. Besides why wait? I've swapped out a set of injectors in under 10 minutes from start to finish.

yea, but any napa, carquest or whatever is fine. they usually have a standard and premium to choose from. I have used both in other vehicles and have felt NO difference between them. From what I have got from the parts guys is the premiums will last a little longer.

Is the neon injector upgrade just a plug and go? I plan on doing it when it gets warmer as well because I thought it was a difficult task.

the iac is on your throttle body. theres 2 sensors with plugs on them, the throttle position sensor which is bigger and flatter and the idle air control which is a goldish round thing. its on the left if your at the front of the car looking at the engine.

2 hex screws take it out and spray with carb cleaner. spray the whole throttle body out too.

Ask for Blue Streak / Standard Ignition parts.
