i have a 94 civic dx 5 sp. with the d15b vtec. sometimes it drives great. other times it doesn't. when i hit the gas the car has power then around 3500rpm it goes sluggish. and then about 6 it takes off again the car doesn't always run this way. the vtec feels like it is kicking in fine. car is running rich. the intake and throttle body is off the d16 vtec. the air charge temp sensor is badly damaged when it came out of old intake could that cause a problem. i raced my friends turbo crx and kept up with him after first installing the intake now it doesn't stand a chance. it does have a tune up. ram air intake. edelbrock headers and magnaflow exhaust the rest of the way back. it now has a new oxygen sensor too. thanks a bunch. i look forward to hearing from you all.

first questions is do you have any Check engine lights?
if so those are the first place to look at.
What ECU are you running?
Something I would recommend trying is pulling your back up fuse(7.5amp) its under your hood next to your battery. Have it out for about 30 seconds. Put it back in and see if there is any difference.
With it loosing power like it is. It very well could be a dirty or bad sensor. I would clean all the sensors on your intake manifold with carborator cleaner. as well as getting a replacement for your damaged "air charge temp sensor"
