Alright, I have almost had it with this. Every once in a while (1 in 3 starts about) I'll start to accelerate out of my driveway or a parking spot and the engine will just start to bog down, It'll lose acceleration like it's about to stall, then it'll backfire in the front of the car (the air intake i presume) and the car will launch forward a bit and drive perfectly normal like nothing ever happened and it won't do it again until it chooses to, the next time I start the car (cold or warm).
I just recently took it to a mechanic and they couldn't duplicate the problem (go figure) but I had them motorvac the fuel injectors and I have noticed more response in the throttle but it still does it. I've changed the TPS, spark plugs, wires, air filter, and I've seafoamed the TB as well as put fuel system cleaner in the gas tank. I plan on pulling out the IAC valve tomorrow and see if I can clean it out a bit, and if that doesn't work, I'm going to check out the O2 sensors. Is there anything else I could check out that might be the cause?
There are no codes.

Thanks.
