The car is running well-but the mivec is not kicking in,it keeps revving past 5500rpm but at around 7500rpm it begins to hesitate.if you park it neutral and try to rev it up to the limiter it wont do it and seems to stop revving around 7000 -7500rpm!any help or ideas?

If you have a speedo convertor/delimiter chip fitted (UK market mph) this is often the cause.

The codes don't match up to the chart. Do the keydance again and see if there is any difference.
here's the codes http://www.2gnt.com/index.php?d=PCM%20Error%20Codes
24 (Throttle position sensor voltage does not agree with MAP)
14 (MAP sensor voltage too low/too high)
Points to the map sensor.
I've scanned a couple pages in my Haynes manual and uploaded them for you. These pages will help you check out the sensors.

More than likely it's the map sensor. I remember when i turboed my car i had major problems with the safc and the map sensor. It would act just like yours does. The ecu doesn't use the map sensor in closed loop mode. Open loop starts at 4000rpms and will start reading values from the map. If it is receiving values not in spec then it will limit the rpms and stay locked in closed loop.
Replace the map sensor and let me know how it turns out.

Get your front end inspected. I bet something's binding in the suspension or in the steering components. Also, have someone make sure the frame isn't bent, which could cause your wandering. Lastly, get an alignment done. If tapping a curb while parking gently can mess up your vehicle's alignment, imagine what crashing it into something/someone does. Chances are you have front end repairs and an alignment ahead of you.

Hi Peter,
With such high revving engines (me being a Honda fanatic) you need to keep an eye on oil levels. Check the level, top up as necessary. Without the correct amount of oil in, the oil pressure cannot stimulate the switch over cam, which takes it to 8500rpm.
Also, please don't rev you car without load (ie. standing still), this causes valve lash and is detrimental to the engine. Again, please do not rev your car hard without letting the oil get up to temperature or it won't last long :)
Once you check your oil, reset the ECU by pulling the battery lead off for around 20 minutes.
Good luck and have a blast. Could you vote for me if this helps you. Thanks.
