I have a 2004 Honda Accord (4 cylinder, manual) with about 150,000 miles. Yesterday it started acting up. For the first 10 or 15 minutes I drive it, it is fine, but then as soon as I hit about 2900 or 3000 rpm the car violently hiccups as if I just slammed on the brakes once and then begins to decelerate. It does not matter what gear I am in, so long as I hit 2900 or 3000 rpm it does the same thing. Now if I shift to a higher gear and am trying to accelerate, it will be fine until I hit 2900 or 3000 rpm again. If I keep pushing on the gas after it hiccups, it doesn’t continue to jerk but it continues to decelerate.  
  
 Now if I am in neutral (I have tested this in my driveway), it doesn’t hiccup but it will decelerate once I hit 2900 or 3000 rpm. Even if I push on the gas harder as it is doing this, the tachometer continues to drop.  
  
 I tried to add some fuel injector cleaner to the gas tank in hopes that I had a plugged fuel injector, but it is still acting up.  
  
 I should also mention that the check engine light is on.  
  
 Any thoughts?!?!?!

The problem might be with a restricted catalytic converter. Since the Check Engine light is on, pulling the codes will confirm if it’s a problem with the cat.
