spark plugs

[Firebird1]

Hello,
my 2010 Camaro SS 6.2L hesitate on acceleration. At the traffic light waiting for the light to change and shift and step on the gas it with two studders then go but no other misfires. My question will aftermarket spark plugs cause the 2010 Camaro to misfire? The dealer said that I need to change back to the original spark plugs (I have E3 Plugs in it now and change the coils to accel coils).

Yes. Multi-electrode spark plugs can shroud the spark resuling in poor flame propagation.

It seems that someone at the parts counter or on the internet misled you into believing their sales pitch that their design is better than the proven design which has been working for over 100 years. Perhaps they would reimburse you for the costs you incurred due to their deception.

A little research might have revealed the numerous cases where these "designer" spark plugs caused this kind of problem. Go back to the stock (or Nippondenso) plugs with platinum electrodes and forget about it for another 100,000 miles.

As Blue has pointed out, E3 are junk. Many, many people have installed them only to make their car run worse.
