Check engine light
i have a 2000 S2000 and i'm getting a check engine light coming on.
the ride is sometimes ruff. the dealer checked it out and said it's a bent valve because the car has been run too hard. they are accussing me of racing the car. now come on guys, this car just runs hard in the first place. and i don't race the thing. my gf drives it most of the time. before that, they said it was mis-firing. and they made valve adjustments. but the check engine light is back. another mechanic said that we're not using quality gas and it's clogging the fuel injectors. now another one is saying the spark plug wires are causing the mis firing. has anyone else experience anything like this? please help.

Re: Check engine light (Draven_Von)
IF it is a bent valve, the car would run very rough. You would be able to hear the studdering at the tail pipe. Yes, it's that obvious. Anything else could result from cheap gas to something else minor or major. A misshift is the only thing that will cause a valve to bend. Not by just driving the car hard, but by misshifting - hitting 2nd instead of 4th when you are hitting 9k rpms.

Here's a novelty idea...how bout checking that CEL and see what the code is that it's throwing? Or would that not make sense?

I'm not disagreeing, but not always does a mis-shift result in damaged hardware. But you are correct, that is something that should be audible in the exhaust, and possibly even with the hood popped and engine running. Depending on how bad it is.
One other thing that you could do is perform a compression/leakdown test.

hes right, just do a compression test (see if its holding pressure) and if its not, do a leakdown (see where its leaking from) YOU LET YOUR GF DRIVE YOUR S2K o.O

Re: Check engine light (Draven_Von)
Just some random stuff that set off the CEL the Berlina I had:
-Primary O2 sensor failed.
-Secondary O2 sensor deteriorated, the tip was loose inside the cat. (changed to test pipe)
-The airhose between the air pump and intake was kinked, throwing a CEL. (fixed in 2 minutes)
Only way I found out is by having a Honda mechanic read my codes.
