You're going to have to be more specific on what your symptoms are. What SES codes do you have? Any other symptoms? Did this start following maintenance like a timing belt change? etc. You should also probably list your trim level and any modifications you might have made.
First, buy a code reader, best tool you can buy if you are a do-it-yourselfer. Then get back to us with the trouble codes for further help. There is a number of possibilities, so having the trouble codes helps narrow it down. Worst case scenario is timing belt, could be something much simpler, like one of the upstream O2 sensors.My car is a gt with the 5 speed and the 3.0, check engine light is on but I haven't gotten it in to check codes. It's very consistent at being inconsistent, as for symptoms it will cut power on hard acceleration, downshifting to go up a hill or around corners and some times just cruising. It has been doing this since I got it and it has no modifications.
I had my codes read multiple times now and every time I get a P0300 random misfire code. I have but a multitude of cleaners through it including Seafoam and B-12. They help but not much. Again cap, rotor, plugs and wires were all replaced. I've had some people tell me a fuel blockage in my tank, a bad fuel pump, bad valves, bad injectors. It's to the point I'm just going to end up replacing all of those. Any feed back and or help is very appreciated.First, buy a code reader, best tool you can buy if you are a do-it-yourselfer.

Anyway, welcome to Club3G!!!
It usually only does it under load. If it starts to misfire and then I put it neutral and rev it its still usually there.Those cleaners are snake oil with the exception of the fuel injector cleaners that you put in the gas tank which can help but its more like a multivitamin not a cure you feel me? I highly recommend the bluedriver, I have one and its great. I know it sounds unrelated but definitely check for vacuum leaks. If you can I'd go ahead and replace all of the skinny hoses since its so cheap, namely the ones from the egr. Are you able to post a video? Does it hesitate like that only under load or does it do it if you drop it in neutral and give it a good blip?
