This is from a workorder I put in a while back:
Interm when cold, engine stalls after start up...idle drops and fluctuates, then stalls.
What is was doing:
When I started the car, it would start normally, then the RPMs on the tach would fluctuate, then the car would stall out.
What it was(I am not familiar with engines, so I have no idea what all this means) according to the work order:
CAUSE: 2783 42 WDS TEST KOEO PASS DATA LOGGER TEST IAC OUT OF SPECS ORDER NEW IAC
MTDIAG DIAGNOSIS WDS OR CHASSIS EARS 3526 WD94
1 XS2Z*9F715-BA VALVE ASY-THROTTLE AIR BY-
12650D3 VALVE ASSEMBLY (IDLE AIR CONTROL)- IAC (9F715/9F670)- REPLACE
Again, I have no idea what this means, but I know it fixed the problem I was having.
