i just changed my plugs and i had do disconnect everything in the middle i never disconnected the battery i put the bosch platnium 4 fusions with the iriudim tip i put everything back together and when i started it up it made a loud tapping noise and my cel was on and trac was flashing while i was doing this a friend of mine like and ediot was playing the radio so he had it on accs the key while i unplugged all the sensers so i disconnected the battery for 5 mins and then it was fine no lights no tap any ideas the car runs a whole lot smoother and a little quicker on acc i like it ?????

 

So are you asking a question or giving your review on the subject....

??????

 

i guess a ?? about the noise

 

Isn't the tapping noise fixed though???

Either way, I would make sure your spark plugs are torque down to spec. Than make sure you put everything back together on the throttle body assembly...
