Default HELP: PO302 code and Honda can't find the problem

So i'm pretty new here guys. I started a thread to introduce my self about a week ago. I bought my 02 S2000 last thursay with 54,000 miles from my local Honda dealership. It had a low idle and mis fire code for cyclinder #2. The next day I brough it to the dealership for the misfire which you can feel at idle with the CEL also showing. To make a small story short it's been 6 days and they've replaced:

1) All 4 coils

2) New plugs

3) Valve adjustment

4) Compression test (passed fine)

5) Leak down test (passed fine)

6) New fuel rail

7) Injectors (to be done today)


From talking to them they said they've never seen a misfire that they can't get to go away. Is there any other paths or advice that maybe I could give them that they might not know? It seems like they're just pulling parts from the car and guessing what's wrong. The mis fre is only at idle, once you're rolling the car runs like a champ. Thanks for your help.....

Timing issue? fuel pump? Other fuel issue? Bad gas?

Little addition, have them check the valves. Specifically look for things like cracked valve retainers etc. While its probably not the problem, its always worth looking at in a used s2000 as its something that happens if someone makes really really bad miss shift.

They also checked the timing, the valves and the rings too. Today they're suppose to look at the injectors and have a conference call with some big wigs from Honda in CA

I hope you dont have to pay for any of above since they didn't fix the problem.

Just out of curiosity, did you buy the car like that?

Yes I bought the car from Honda like this and it was part of my agreement with them for the mis fire to get fixed. I received a phone call today from them and they replace the fuel pump, fuel filter and drain the tank of gas and finally replace the injectors. They say the injectors was the problem and I'll be picking it up tomorrow for inspection. Oh and yess all this was covered by my local dealership for free

LOL, Yeah today is day number 8 since they've had it and I'm suppose to get a call from Honda today saying to pick it up. After all the parts they replaced trying to find the problem I don't have very much trust in them in the future. Can you imagine if I was paying this bill and what it would look like????
