My 95 Accord LX bucks after the engine has idled and warmed. Once the engine is warm and RPM the drops to the normal RPM, the sound of the engine changes and the car runs rich 12-13 AFR then it goes back to 14.7. If I drive the car after this happens the car bucks at light throttle (due to running lean) and if I apply more throttle it runs fine. The problem is intermittent and goes away if I stop and let the car idle for a minute or two. Plugs and wires have been replaced I'm leaning toward the IACV or clogged EGR ports. Any help would be greatly appreciated.

 

I hate these issues because I am having them myself but my car was fine before I replaced the dizzy and did the timing belt.

As for your issue have you properly gaped your spark plugs, is your timing on point. Your fuel filter could be clogged, your cat could be clogged or you may have a vacuum leak and there are so many variables to this issue it hurts my head.

Since you assume it's the EGR ports or IAC start with that.

Did this issue randomly pop up out of the blue?

 

The problem just started recently and I'm not getting any error codes.

 

Since this appears to be related to the egr system since it only happens when the car is warmed up I would clean out the ports and egr valve first.
