I thought I was nuts, but it kept happening when I went to floor it.
Still scratching my head, I was about to schedule a trip to the dealer. Fortunately for me, I have to save my gas reciepts and there you have it, I filled it with 87 2 days prior.
I drove it out on the highway (and got a little LESS MPG than normal, and I wasnt romping it) filled it up with 93 and the car was fine.
87 and HOT weather (FL) will do exactly this - retard timing to degree that you will notice. Good post.
