1998 3.0 skipping
 

I've replaced the cam syncronizer, the cam sensor, and ecm. I still have a skip and get the p1309 code intermittently. I'm also getting a p0141 O2 sensor Cade can this be my issue or am I missing something else.

Welcome to the forum

The Cam sensor timing is tested by comparing it to the Crank Sensor timing, Crank sensor is the main sensor, engine will not run if its not working

So P1309 usually means Cam sensor is not timed correctly
If cam sensor was failing then you would get one of these codes:
P0340 Camshaft Position Sensor Circuit Malfunction
P0341 Camshaft Position Sensor Circuit Range/Performance
P0342 Camshaft Position Sensor Circuit Low Input
P0343 Camshaft Position Sensor Circuit High Input
P0344 Camshaft Position Sensor Circuit Intermittent

You should NEVER EVER google a specific code number, look up codes on a FULL LIST, this will show you what "other" codes the computer could have used, so can narrow down why it chose the code it did

The 1 instead of 0 after the P means its a Ford specific code, not a general code, because general ODB code, 0309, was for something else

Full list here: OBD-II Trouble Codes : The Ranger Station



O2 sensors have 4 wires, 2 for the sensor and 2 for the Heater, O2 sensors must be above 600degF to work, so they are heated by a coil heater inside the sensor housing.
The computer is the Ground for each O2 sensors Heater circuit, so it can "see" if each O2 heater is getting 12volts

P0141 02 Sensor Heater Circuit Malfunction (Bank 1 Sensor 2)

Bank 1 is passenger side on a V6 or V8 engine, or only side on 4cyl
Bank 2 is driver side

Sensor 1 is the sensor closest to the engine on either side, called Upstream O2 sensor
Sensor 2 is the sensor after the Cat Converter, call Downstream O2 sensor

So Bank 1 Sensor 2 would be the downstream O2 sensor on passenger side, after the Cat

Best guess would be one of the heater wires is broken, melted
And no this wouldn't cause rough running, but it is part of emissions system, Downstream O2 checks if Cat is working


And just as a future heads up
Electronics rarely fail, not never, but it is not usually the problem when engine is not running correctly, 90% of swapped out sensors were working fine, for some reason people seem to think swapping out electronics because a "code" mentions them is a good way to do things, it isn't.
Gasoline engines still work the same as they did in 1901
Gasoline
Spark
Compression

If engine is running rough, or not at all, then problem is one of these 3 things
The electronics just made 2 or these 3 things more reliable, spark and fuel
