Did you change the PLUGS
I found the front ones need changing early 0.70 on front bank after 56,000 miles !!!!
Just do the front if your mileage is similar
The rears were OK 0.63 !!!!
Never changed the plugs, I just bought it like 4k miles ago and I do not know if the previous owners changed them, actually the last saturday I check one to see if there was any damage and they looked fine but with a very thin electrode, I'll try double platinum ... maybe this weekend.
Any other ideas??
