[Supras] Setting Idle Speed, '88 &M-GE

[supraman88]

After the plug/wire change, it seems to be idling high (1,000-1,100 
RPM.) I checked the TSRM and a Haynes manual, and the only thing I can 
find is setting ignition timing. I will check this later today, but I'm 
used to the older Celicas with the 22RE and a couple other FI models 
that had an Idle screw. Not found on the 7M-GE? Interesting...even my 
4A-GE has an idle adjust screw...
