The new plugs for the recall come packaged in a"kit"along with the stickers etc...no chance of getting them mixed up.

 

What causes the "stumble" when coming to a stop? I thought it was related to the MAP sensor so I removed the sensor, tapped on it, and re-installed it. The result: nothing different.

My car does seem to idle a bit smoother and the stumble has lessened since I had the spark plug TSB done.

 

Had mine done this A.M. Butt dyno sez' it's exactly the same. I do hear that the Iridium's give a slight hp/tq. gain though.

 

No difference on my butt dyno...
