What is this? Sometimes, when I press on the accelerator a bit then quickly let off then immediately press it down again the engine seems like it "misses" or "backfires," even though it doesn't seem to actually backfire. I don't know why it does that.
my car does the same thing. I cant figure it out either. i have just learned not to hit the gas hard when less than 1500 rpm. putting in my 3600 stall made it less noticable by far so untill it goes to the shop for another reason ill live with it as i have spent many hours and threw money at it with no sucess.

Hell that sounds like the timing and throttle are out of alighnment when you hit it again. Maybe this could be due to a stretched timing chain? I have had this problem with a couple of older high mileage vehicles, slop in the chain.

I had that same problem. I would have a huge surge/miss/backfire, same RPM range, usually at highway speeds 55-60. Around that time my transmission went out. I had it replaced. That problem has not resurfaced. I still do this day do not know why it happened. I'm glad I don't have that problem. My O2's are pretty contaminated too.
