I replaced the OEM plugs today on my sonata. Piece of cake. Installed Autolite Iridium XP plugs. Car runs perfect.
OEM plugs looked fine..
No difference in pinging, took it up some hills and inclines around Austin TX, pinged badly under load going up hill with 89 top tier in the tank.
Filled it with 93 and zero pings, not a single noise.
I think the tuning in this car is wonky and probably related to CAFE standards. I think the OEM tune is throwing the transmission into a high gear super early to keep the revs low, and it is lugging the heck out of the engine every chance it gets.
That is contributing to the ping condition (my guess)..
When this engine lugs is when i get a ping usually.
Do not use the stupid eco button on the dash, that will just lug the engine even more.
I wonder if anybody tunes these cars, at least the transmission shift points to reduce it from lugging so bad.
Car runs perfect with 93 octane fuel and new plugs. Wife even said it was "fast" when she drove it. I laughed.
