Maytag,
I agree with some of what your saying.
If you have ever read any of my previous posts I very often suggest that a person check and prove good or bad the simplest things first and work their way up the diagnostic ladder step by step from simplest to most complex.
I first started trying to help Kbod in another thread that addressed the same issue he is describing in this thread.
In both threads he has stated that he gets a reoccurring P1341 code. Bank 1
Lumpy idle after warmup and stalling at stops.
He also has excessive Cam deviation on Bank 1
Vacuum leaks are very simple and basic and can cause lumpy idle and stalling.
That is why I mentioned Vacuum leaks to Kbod.
Many time they only cause lumpy idle and stalling after warmup. Why?
Because on cold start open loop the DME is providing a very rich mixture with no feedback from the O2 sensors. Tends to compensate for the unmetered air from the vacuum leak, so the car may idle just fine.. Once the system warms up and goes into closed loop the mixture leans out and becomes too lean at idle because of the vacuum leak. So you may get lumpy idle warmed up but not on cold start.
What I first suggested to Kbod was to check for any wiring issues related to the Cam position sensor on bank 1
Why? The P1341 code.
Checking the wiring and testing the Cam position sensor would be my starting point.
I don't know how to go about testing a Cam position sensor. So I suggested replacing it.
Seemed the simplest, most basic most logical and cheapest to me.
I mentioned Cam timing because Kbod had replaced the Actuator on bank 1.
and still has the issue.
Not sure how I am barking up the wrong tree.The P1341 code gives a good tree to bark up
As for the MAF sensor and vacuum leaks, which either could cause the lumpy idle.
I told Kbod I can tell him how to test both the MAF and possibly for vacuum leaks with his Durametric after we see what affect changing the Cam position sensor has.
Although I don't think the MAF or vacuum leaks are the issue.
Not sure what squirrels I am chasing.
But I could be, very hard to diagnose an issue via the internet.
