Idle speed spec for a manual trans car is 790 RPM with the AC off, 800 with the AC on. Tip cars are 790 RPM for either.
As your car is an egas version, the idle speed is controlled by the DME and therefore not adjustable. So if it is idling at 650 RPM hot, you need to be looking at why it is idling low.
You can use the Durametric fuel trim values to determine if it is either lean or rich:
The key to the adaptation values is as follows:
RKAT = Adaptation in range close to idle Cylinders 1 - 3
RKAT2 = Adaptation in range close to idle Cylinders 4 - 6
FRAU = Adaptation in lower load range Cylinders 1 - 3
FRAU2 = Adaptation in lower load range Cylinders 4 - 6
FRAO = Adaptation in upper load range Cylinders 1 - 3
FRAO2 = Adaptation in upper load range Cylinders 4 - 6
FR = Oxygen sensor for cylinders 1 - 3
FR2 = Oxygen sensor for cylinders 4 - 6
You can also use the Durametric to check the MAF values to make sure they are in line as well.
