bucking is spark
fuel loss in like is smooth and gradual.
next time it stalls, with scan tool hooked up,, just pull over. and leave key on, and check for DTC errors, while key is on. still.
i dont think the tool stores pendings. (I DONT know for sure)
you press the keys for pending and it scans the PCM for just that, and shows you if there are pendings or live DTC errors.
If the failures are solid , the PCM stores them in it's DTC RAM. and will no clear until the , x number of driving cycles, each DTC has its own drive cycle count rule .
some clean too fast.
P0300 will stick there awhile, P0300,301,302,303 and 304, (300 is misfiring all 4, 301 is cylinder 1. etc.
the 340 and 355,IIRC, they love to reset fast. (CAM AND CRANK SENSORS) THAT I SUSPECT NOW.
the PCM if it sees, the CKP sensor fail, it will store it but if it sees it go away fast, it clears fast,TOO,, same with CMP sensor.
that is why the Pendings are so key for CKP/CMP..... FREEZE FRAME IS HANDY TOO, it shows what other key sensors did, at the last DTC stored.
Freeze frame is like looking in a key hole.
are you sure your COP boots are ok.?
pull the cops make sure there are no cracks or carbon tracking in the boots.
take a look at the CMP sensor, do you see a bolt there for it, and any wires black to any CMP mounts or bolts there, (besides the connector )?
tricks to try, simple.,
remove the CMP, on the end if it can be mud, this mud is metal dust (iron) and if it builds up it misfires, wipe if off with a rag and its fixed. a zero buck fix.
same with the cranks sensor , both are non adjustable. a blessing that.
if a cop fails, you get like 1/3 horse power or less, 2 cylinders dragging 2 dead is way less that 1/2 power,
im really sad the PCM will not pop P03xx errors... it must if you do it right, leave key on, wait say 2 o 5 minutes and scan the stalled engine, a DTC normal scan then pending scan.
be so cool to see that, and we can nail this flaky part what ever it is.
some folks get so mad, 2 new cops/ckp and cmp. Im sure it's thermally related. gets hot and fails. sure seems so.
Pendings are DTCs real, that are not stored in PCM memory yet,, its on the threshold of failure.
good luck in your testing ! cheers.
