Chug Chug? or Car Miss Firing

[Sick Blue VL]

Hey guys,
I was at the lights the other night and it was runnign fine up until i hit the gas at the lights not heavy at all and then it sounded like it was chuging like a train or something
it would still take off the same and everything but with the brake on and everything you could fell the car moving a bit like if someone was at the back pushing down on the boot a bit. Not much but you could still feel it. and you could also fell it in the t-bar auto?

any ideas would be great thanks sorry i could not explain it any better.

I'm new too - since joining about 2 weeks ago I have got one feedback from the more experienced members.

In the mean time I have bought a VL to teach myself on.

Simple test you need to do - something to rule out.
Access computer. Turn screw anticlockwise.Start car.
Run at 2000rpm. If your green led doesn't flash every 2 seconds then it is likely the oxygen sensor is crap. - This test is free. Let me know how you go.

My injectors were leaky - this was leting air in. My idle was increasing all by itself to about 1500. I had to find the air leak as adjusting the idle screw did work long term.
