Mine happens at all temps at highway speeds when I let off the gas then accelerate - you can feel it stumble - and it only happens on cyl 7.....here is the freeze fram data from the P0307

RPM's 2283
Load Value 23.1%
coolant 201 dgrees F
short term trim1 0.0%
long term trim 1 .8%
short term trim 2 0.0%
long term trim 2 2.3%
short term trim 3 -100.6% (ouch)
long term trim 4 -100.6%
short term trim 4 -100.6%

vehicle speed 59MPH


does that point to the injector stuck shut on 7?

 

Does anyone know what this ffeeze fram data mean for at DTC 0f P0307:

Here is overview:
1. Codes pulled PO171 'too lean' + PO130 bank1 circuit 1 + PO150 bank2 circuit 1 + P1171 No DTC see service manual + P1300 ignition timing adjustment terminal.
--K&N OE replacement air filter a few months back
--Oil change done 3 weeks ago with 5w40 T6 Rotella & K&N oil filter

2. I understand the 'fuses' and 'wiring' under motor to oxygen sensors need to be checked and could be an issue if fuse out or corroded.
--Will be checking the fuses today to see if any bad or wires messed with in case could be that and oxygen sensors not need to be replaced.

3. I have noticed that fluid levels have to be watched every month now and slightly fill needed every 2-4 months.

4. I changed the plugs an put iridium new in + NGK plug wires and had to remove the upper intake manifold to reach ignition coil cause top two bolts were not attached.
---Noticed afterwards some water around manifold front where the hose attachment was and could have simply been from removal of hose and re-attachment + BUT there was slight oil around this front section of where the manifold bolt goes.
--Is that abnormal? Should I check something upper section for oil issue with a gasket or anything?

5. Besides the two oxygen sensors down below is there another oxygen sensor this code for Bank1 circuit 1 or bank2 circuit 1 could be pulling from?
--The right rear bottom Oxygen Sensor I replaced a few months back.


I thank you for all your help in this matter.
