So last night I drove slightly out of town to look at another Z. After looking at the car, I hopped back in mine and hit the road. As I was rolling at 65mph on the interstate, I noticed I was pushing close to 6000 RPMs. At first I was afraid my OD was out, so I screwed with that for a second, and then I realized that in the confusion of being in an unfamiliar city, I had accidently pulled my automatic trans. down into second. So I'm out driving around later that night and I hear this clicking noise that is coming from my car. At first I thought it was an injector and then I hoped that maybe it was a valve and that maybe my oil level was low for some reason. Then I freaked when I thought that it could be a rod...well, it turns out it's the injector. So I'm at work today and when I get back into my car after lunch, the injector noise is gone. I was all excited and decided I would simply clean the injectors this weekend and hope the problem never comes back. Well as I was coming home from work, the noise started again. If the noise went away and came back, is it possible the injectors just need cleaned? Or is it likely that I am going to need new injectors? The car has 124,000 miles, let me know what you guys think.

Thanks,
Jacob

How did you come to the conclusion that the injector was bad?

Have you had the injector saftey service campaign done yet?

I put the tip of a screwdriver on top of the injector and noticed that the injector pulsated with the clicking noise. I am not sure about the service campaign, I meant to call today but did not have time. I will call the dealership in the morning. Do I just give the dealership the VIN and ask them to see if all the recalls were done?

Thanks

How big are the stock injectors (how many cc's?)? Anything wrong with slightly larger injectors on a stock engine running about 10 pounds of boost? Anyone have another comment on the coming and going of the injector noise?

Thanks
