VTEC HAS GOOD DAYS AND BAD DAYS?
I have a bone stock s2000 that just turned 23500 miles. My vtec is really strong some days and other days it seems that acceleration 6-9000 rpms is definitely not a constant pull. I have always changed my oil every 3000 miles and i rune standard conventional oil. Yesterday my car was acting up then today it went away for the morning and started to act up again this afternoon. I always run 93 octane gas too. Is this a common problem? Btw the car idles perfect and drives well. I just dont get it.

Sounds like the old 'MAP sensor' problem . Whacking it did'nt always fix my problem(your's), I had to ,sometimes, disconnect/reconnect the sensor(after a whack) to clear the problem.

boostjunkie, i'm in wisconsin, also in the midwest.
my car has been somewhat the same lately, and really it's the weather/heat/humidity. could be the map sensor as someone pointed out, and there is the map sensor whack you can do. (in the technical forum, at the top there is a sticky with FAQ's and HOW-TO's)

I dont like the idea of tapping on a sensor to get it working so I just went out to the hpnda dealer and I ordered a MAP sensor. I will let you guys know how it goes after that. thanks for all the help

I totally agree that 'whacking' the MAP sensor...or any other sensor is not the ideal solution to ANY problem with air/fuel management when troubleshooting any late model car. This solution to an erractic 'idle return' problem always annoyed me. I've found that disconnecting the MAP sensor and reconnecting, corrected my problem. Apparently, it seems that the PINS were a little corroded and by disconnecting and then reconnnecting, the PINS had fresh connections and then opperated correctly. Hey, worked for me. As far as the phenomenom of 'heat soak', well, the best advice I can give is to try and lower the temperature under the hood as best you can.
