I have a 2000 Honda Civic Si. My trouble is the car has loss all power and can barley make it up a hill. just the other day vtec was working and now it isnt. it feels like its hitting the rev limiter at 5k rpm and is getting worse by the day. ive done somethings i thought may cause it but didnt help. i put a new fuel filter on it checked the timing checked all spark plugs replaced 2 bad o2 sensors with ngk ones.checked all the vaccume lines. i also done a compression check and everything was ok there. i have NO idea what it could be and cant pay a shop 100$ an hour to diagnose it. and there is no CEL. Please Help!

 

does anyone have any ideas that may help?
