Check engine light just started blinking. but stops and stays on only when not moving.
P0303 cylinder 3 misfire
P1763 skip shift solenoid circuit
A blinking check engine light usually means exhaust system
No engine stated.??????????
303 is gross misfire on #3 cylinder. on all cars.
its a for sure thing, means bad combustion on #3 and its power is weak. 1763 is tranny The 7 means that. and is problem2.
ever get a 60k miles tunup this decade?
sparks plugs, spark wires, filters, air and fuel>?
spark plugs dont last life of any engine.
THE CEL blinking (oper guide tells) means that misfire
is burning the CAT converter to a crisp. (raw fuel + air does that)
the opr. guide says get it serviced, fast, dont drive fast or tow anything. all great advice in the glove box.
get a cheap tuneup, and magic can happen in most cases.
misfire has many causes. over 20.
but a tuneup not done, is 99% cause. (due to nobody doing them)
only fate , determines truth, not statistics....
for example you sucked a valve on #3..
if the new spark parts dont fix #3 a compression tests is next.
or an injector balance test say from #3 to one other injector.
all this is like 1hr work, but no engine stated, so.....

Check the cylinders Commpression. over 115 psi is good, 120 psi is normal.

You say you changed the cam sensor. A1391 code is a crank sensor on the top of the trans. bell housing.
SOURCE: I have a ODB II code reader giving p1763, p1762, p0303
Your right about the two codes. It's really a transmission part.
As soon as you open up the transmission pan, it right there.
But, I would leave this up to a transmission place. It may need a special type of calibration tool for the new sensor.
As for PO303, that is a missfire in cylinder #3
I hope I answered your question.
SOURCE: 96 Jeep Grand Cherokee diagnostic codes P1762 and
governor pressure sensor in transmission is the likely problem
SOURCE: Jeep Grand Cherokee 1997. Getting check engine
Code 12 = Recently disconnected battery
Code 14 = Coolant sensor high resistance or shorted
Code 43 = Knock sensor or Electronic spark control circuit fault
Code 55 End read code.
Hope helps (remember rated this).
