A few days ago I did a WOT run. It hit the 1-2 like normal, but when it should have hit on the 2-3 (about 5500 rpm) it seemed to keep going just a little longer and didnt sound all that great, but it did hit hard on the shift as usual (wheelspin at 50-55 mph). I didn't think of it much until I got home. I revved it just a little in park and let off real quick, and I could hear a slight backfire. Next time I drove it I turned the radio off and listened, the motor seems to have a slightly different tone than it did before. It still has plenty of power, I dont have a problem getting the tires to spin, but it just doesn't feel quite right.
My first thought is bad lifter/valve, what do you think?
