Hey guys i got an irritating problem.

Well, lets start with how i think it happend.

I drove from Mass. to Florida and while in the N.Y. traffic my car started stalling and sputtering.

I got it going, and in N.J. pulled over and checked out the fluids and stuff. Was ok, i just had an oil change, new belt, and trannny fluids done.

But, the check engine light was on, and it never had been on before. It stayed on until i got off the highway, in Florida.

Ever sinse then if i dont put 93 octane in the car pings.

Thats the only problem i have ever had with it, except the rotors keep warping....

Any help would be appreciated.

The car just hit 60k miles, but has been doing this for 10k miles.
