I X'd the dealeship name from the thread...

Approximately 3 weeks ago my 2002 Honda S2000 engine light came on so I drove the car to XXXXXXXX; a local car dealership to find out the problem. Once the service department technicians ran a diagnostic test on my car codes P0307 and P0303 (Misfire) came up so I was told I needed a tune up (plugs changed). I declined the work from the dealership because of the $250.00 price tag but, I immediately drove the car less than 4 miles to another local Honda service shop; XXXXXXX. I chose them because a few years back the service department at XXXXXXXX referred me there when I was looking to get a Comptech Cold Air Intake installed. XXXXXXX did the required tune up (plugs changed) and cleared my engine light but less than a week later my engine light came back on. This time I turned to the dealership (XXXXXXXX) to get the work the completed and I was told I needed the Platinum OEM plugs in my car and everything would run great. Needless to say I spent the $250 bucks because I needed to resolve this situation

If you can find a bottle of redline fuel injector cleaner, try running a bottle through.. or maybe they gapped the plugs wrong

If you get the dreaded misfire in all cylinders, usually means your valves are bad. I got the misfire code a handful of months back and in the end it needed valves. A quicker way to find out is to do a compression leak down test, if the test comes back bad then you gotta start pulling parts off, if the test runs great then one of the aforementioned suggestions should take care of the problem. Note: my mechanic said that my valves could have been damaged because of the wrong plugs in my car but was most likely due to overrev by the previous owners and it slowly got worse. My car as far as I knew ran fine even with the light on and such, and when I got my car back it still ran almost the same (although the Vtec switch was a bit more aggressive) and truthfully the damn tapping sound is still there. Apparently a little tap is good and our injectors are quite loud.

All the X's is the dealer I went to...

Thanks for all the feed gents... I went back to the dealership with all the information I have been reading on S2ki and he started singing a different song... I used some injection cleaner and so far so good...
