i have a 1999 honda accord v6 2 dr. recently i went to the dealer to get the egr drilled. it was running fine for about 2 weeks but now its running odd. sometimes there would be a slight hesitation when i start the car and drive. 2nd the idle is lower than normal sometime it would be at the at first line you see after zero. eventualy the car would correct itself after 10 mins of driving. so if i drive the car down to honda i'm afraid that they will just say nothing is wrong and be a waste of time. anyone know what to do?
