Engine has started slowly in the past; most recently would low RPM stall, will not idle. Runs fine otherwise; codes checked 0102 and 0107. Replaced air flow meter and did not help. Could it possibly be map sensor or any other ideas - possibly loose timing belt?

Yes you need to replace the MAP sensor which is "BOOST PRESSURE SENSOR" That will usually cause a low idle and stalling problem. Good luck and keep me posted as to what happens. Make sure you reset the codes after as well.

JIS001 - thanks for the help. I ended up replacing the Idle Control Valve and it is now working properly.
