I did not change the sensor. The Camshaft solenoid it at first like most people there was oil in the connector and it was not only clogged but stuck in there good I suspect its original. After installation of the CPAS the check engine light went off but the stalling happened again tonight a day after I put it in seemed like it was running great the code is not popping at all when before I would clear it to see what condition it came back in usually under the stalling and today it never.
My truck seems to be running at 96 - 94 C, 201-205 F it does have horrible mileage I only have a Bluetooth scanner but from what I notice is when is sometimes it says open loop due to insufficient temp.
I'm going to change the fuel filter and test the fuel pressure but I suspect it is OK under idle when your not stopping it never stalls. The only time it usually stalls is approaching a stop or accelerating and than it bogs down but it some what seems like maybe too much gas is being dumped in and than its taking too much away because the fuel trims go all whack so it leads me to believe its not the fuel pressure but you never know.
If I have the push the pedal to the floor it it will pretty much never die but living in a city you do have to stop often so that always hard to do when your stopped.
I'm thinking possibly a faulty cam sensor, fuel pressure regulator, thermostat, or oil sending unit could cause symptoms like that. I am not the original owner but it seemed that most things were done that needed to be a trouble than they gave up.
Things I have replaced or done:
CPAS - Camshaft Position Actuator Solieniod - AKA VVT soliniod - It had oil in the connector and was stuck so it was time to be changed after 219,000 KM
Done an engine flush changed oil filters right before installing the CPAS
Got a new catalytic converter the old one was clogged which I suspect was caused by whatever underlying issue is going on.
I got a new o2 sensor which I think is just crappy its an NGK which apparently are the same maker of AC DELCO but it seems to be off so I'm going to return that and get a new one because the readings go real crazy the connector is perfect and all the wires going too and from is fine.
Had a new alternator put in because the other was shot
What I am going to do -
Visually inspect the crankshaft position sensor and I seen a handy video of a voltage test on line to actually verify if it is working correctly to this point I never even unplugged the sensor because I wanted to try the other part as it was really clogged anyways.
I'm going to somehow test the fuel pressure regulator and see if that helps and the fuel pressure
I'm going to visually inspect the thermostat but after 219,000 km or 136,000 MI I would suspect they would start to fail after so long.
Figure out a way to know if the TBS is actually not actuating or working...
and take back the o2 sensor and get another one and because the connector is fine.
