I noticed when i was sittin at a light that if i just tapped the gas the rpm gauge would go up and then go back down below idle and start to shudder and then do it a second time. it only lasts about a second. Anyone know what could be causing this? thanks

The engine speed drops a little low after you tap the gas, sometimes the car will shudder. Then the IACV will re-adjust it back to normal. Don't worry about it

My accord was doing the same. Found out the map sensor was bad and the a/f ratio was way off. The car was running rich and it was choking the engine. Good luck.

His symptoms does not sound the same as your car. A bad MAF sensor will cause a check engine light. If you tap your gas pedal or u push it down slightly and hold for a while, then let off. The car will shudder for a little bit before the IACV can readjust the idle speed.
