1998 Honda Accord F23a1 Vtec 150 HP

Here is the problem:

After going through the gears, and letting off the gas(like when you come to a stop sign) the car's idle will drop and almost stall. A few seconds later it pops up again. It has NEVER done this when I rev the car when stopped, only happens during driving.

I have replaced:....plugs, wires, cap, rotor, and fuel injector cleaner...

Result: Idle is not speratic, nor lower then normal any other time then when the problem occurs. I have a cell code 67 which indicates a random misfire. The cel will go away and not return for hours if I reset the computer but even without the cell, the idle problem is present.

Any ideas will be appriciated greatly!!!!

 

Good question: I have that same problem, only since it got cold out in chicago.

 

Trying running Sea Foam through it.

 

could it have something to do with the fact that the cat has blown out? Seriously, I didn't do it!
