I'm gonna break something. Yesterday I had been driving my car for about 20 minutes then I stopped at the store. When I came out and went to take off my car...stuttered. I didn't think anything of it at first but it kept happening everytime I would stop and take off again. At first I thought that I was just being stupid with the clutch but I had it happen twice while I was moving at about 40mph. I have found out that it only happens when I have my AC on. I done a TB bypass about a week ago but I've only driven it about four times since then. I guess three as of yesterday. Could this have anything to do with it? I also notice a BIG change in hp when I turn the AC on. I didn't notice that either until after the TB bypass. I just changed my plugs and wires about three weeks ago so I don't think that is it. I don't have an SES light. And, it only does it when its warm???? Please help????

Thanks,
Jason

Not sure as to the studder, but regarding the loss of power when the AC is on: it's because the AC compressor is running. Having the AC dramatically reduces power. Use the vents instead.

I've been using my AC here for about two months now and I never noticed such a dramatic change in hp. I know that the AC uses a lot of pony's but this change is something like you would notice on a rice burner or something a go-cart engine.

I think your might have a loose spark plug wire or spark. Looks like the engine misfires at those times due to a loose wire or something, therefore shuttering at take-off. TB Bypass shouldn't cause such a problem.
