I would normally go to the Hyundai tech site for this, but since I've last
looked, it seems to insist that I register first, and then it doesn't every
respond with the email that it promises me... COOL!
Anyway, I have a couple questions. What is the correct spark plug torque
for the 2002 Elantra GT?
Second, Using a guess at the torque, I installed a new set of plugs at about
13.8 lb-ft, and the car now sputters and backfires. I put the old plugs
back in, slight hesitation at idle, but not running that bad. Replace one
plug, slight hint of a sputter. 2 plugs, backfires again. Old plugs back
in, runs as before. I'm beginning to think that you just can't replace
plugs in one of these...
The replacement plugs I'm using are Autolite Platinum AP 3924.... supposed
to be the right size... what's up with this??? Could the entire set of new
plugs be bad?
BTW, I have just over 60K on the plugs (yes, I'm looking at getting it to
the shop for a new timing belt in the next few weeks.... )
