I'm looking for any hints on what might be wrong. The problem is that after the 93 Pathfinder is running warm, typically freeway driving, when it then gets into stop and go traffic, the idle drops and it stalls out. That is, when coming to a stop, and the foot goes off of the accelerator, the car stalls.
When just running around the neighborhood, problem does not occur, only after engine has been running for at least 1/2 hour.
This has been happening for the past 3 1/2 years, and it has been fixed in 4 different trips to the Nissan dealer. So this will be the 5th trip to the dealer, as it's started happening again. The sympton is always the same, and the dealer has fixed it each trip into the shop.
Looking at the work orders, the dealer has fixed 4 different things,
1st trip - Idle air control valve
2nd trip - tune efi, replace throttle position sensor, wynn's complete fuel system flush
3rd trip - tune and replace aac valve
4th trip - replace cpmn
It seems odd to me that the same sympton would be fixed by 4 different things. Would anybody care to offer any suggestions on what the real problem might be.
Thanks
