Hello, I have a 2002 Nissan Pathfinder that I recently bought for my son. We are having quite a bit of trouble with it cranking. The exact diagnosis from the local repair shop is as follows:
Finding:
Engine idle unreliable. No DTC's at this time.
On first start and every subsequent start the
engine starts then stalls, if the accelerator is
tapped while starting the engine will continue
to run and idle. Fuel trims are in zone and
mass air flow is in zone. The throttle body is
cable operated and requires an Idle Air flow
Control solenoid (IAC). the IAC controls the
amount of air that is available to the engine at
idle, this is necessary because the cable
operated throttle blade is closed completely at
idle. If i shim the hard stop by 0.002" the
engine will start and idle, but the idle is higher
than it should be. Inspection found the
appearance of a new IAC valve and the
connector is highly corroded.
!
The Valve has been replaced, but the repair shop is telling me the connector also needs to be replaced. But they cannot locate a connector, because it is no longer manufactured. Do you have any after market recommendations for finding the part? I also included a picture if that helps.
