my crx has been running a little rough the last week or so. when i'm on the throttle in the lower gears just starting to pick up some speed 20-30 mph, it will bog down sometimes, almost like it wants to die. i'll have like no throttle response and almost come to a stand still. i then usually slam on the throttle and it comes to. what would be causing this problem? when i first bought the car, before the b16a swap, i had the same problem with the d16. although this has just occured in the last week or so with the new engine in. i personlly have only put about 200 miles on the motor sense it was installed. anyone out there that knows what is going on please help me out.
