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
