hey so i think i have a big problem
so this is my first post and i thought that i would start out with a good one. i bought my 02 s2k round christmas of last year used with about 75000 miles,yeah i know its a litte high but its what i wanted and what i could afford. anyways bout 3months after i started to notice a rough idle and a honda tech told me it was more than likely spark plugs. ok, well changed them and it was still there, but this time i threw a check engine code. so i took it back and they told me it was a miss fire on cylinder 1 and they did a leak down test. it came back with like 75 psi on the first. so they said it needs the valves to be adjusted. ok so had that done. still didnt fix it. then they said it had to be a bent valve but they wouldnt know till they got into it. so i pulled the head took it to a shop and told them the diagnosis and it came back fine. no bent valves and good as new. put it back together and it still does it. it threw a code again so i took it to a different dealer and they did the same tests and told me the same thing $1600 bucks and we can jump into it. im at the end of the line and need some help bad.

Ok. Here is a translation.
Rough idle
CEL for miss fire
Compression test, 75 PSI on 1
Dealer said, Valve Adjustment. Did not fix
Dealer said, bent valve. Owner pulled head and dropped off at mach shop.
Owner reinstalled head, same problem.
Took to dealer, compression test again low.
Sounds like scored clyinders to me. Time for a new short block.

Your head is probably trashed. IMHO this is VERY common on AP1's, happenned to mine before the warrenty ran out. I'd find a reputable swap to help rebuild the head, maybe throw some bigger cames in, hard to say with that 9K redline...

I had a similar problem and went through a similar diagnosis. After changing plugs, injectors, coils etc I found I had low compression on #2.
A pull down showed I had cracked rings. Required a complete rebuild.
If you've had the head off and checked for straightness I won't be surprised if yours is similar.
