Default LS1 running at half power - need some hints

Hi All,

Today took the Cobra for a run and its like somebody turned on a 50% power switch.

Am looking for some hints on troubleshooting (short of taking it to an expert).

Essentially when I accelerate its like its running on 6 cylinders.

Also when crusing along at 100Kph it is rough when you increase the power slightly.

So Far I have checked the following:

1. Fuel Pressure = 59psi - stays the same when you put your foot down
2. Put my ODBII DashCommand etc logger on - nothing of note comes out
3. Checked all plug leads are on tight (one looked a bit suss so I removed and reconnected - no change)
4. Checked all engine loom connections to things like TPS, MAF, etc


The only other things I have done since I last used the car a week ago is that I disconnected the battery whilst fixing my stop light switch.

You havent heard of the ECU going into a weird mode if the power is removed??

Other than that anyone know a good LS1 guy in MElb Eastern suburbs.

Thanks - pls no ford jokes.

Rgds

Gregg
