error code p1310 ???

This is what i was able to find, I am sure someone else on this forum will guide you. It may be a misfire,ignition coil or a fuel injector.

Thank you...
I'm a little confused... My new OBD II pkt scan says I have 3 error codes
p0300
p1310
p0300 p/d
I know the 0300 is misfire detected.
p1310 is a ECT.
I've installed all new plugs and two new coils. So at least the error codes are not cylinder specific. Just not sure why it still says misfire.

Try clearing them all and on first CEL check the code ... At times one bad code leads to another.

Okay...
I've cleaned the connections and cleared the codes. At idle the car sounds great as I slip into gear and start to move the codes hit and are P1310 and a pending 0300. The car is responsive until 3000 rpms when it then gets really herky jerky.
EDIT: Just found this out on the WEB and it explains alot.
P1310 Igniter Circuit Malfunction No.2
CIRCUIT DESCRIPTION
The ECM determines the ignition timing, turns on Tr1 at a predetermined angle (°CA) before the desired ignition timing and outputs and ignition signal (IGT) 1 to the igniter.
Since the width of the IGT signal is constant, the dwell angle control circuit in the igniter determines the time the control circuit starts primary current flow to the ignition coil based on the engine rpm and ignition timing one revolution ago, that is, the time the Tr2 turns on. When it reaches the ignition timing, the ECM turns Tr1 off and outputs the IGT signal O. This turns Tr2 off, interrupting the primary current flow and generating a high voltage in the secondary coil which causes the spark plug to spark. Also, by the counter electromotive force generated when the primary current is interrupted, the igniter sends an ignition confirmation signal (IGF) to the ECM. The ECM stops fuel injection as a fail safe function when the IGF signal is not input to the ECM. DTC No.
DTC Detecting Condition Trouble Area P1300 No IGF signal to ECM for 4 consecutive IGT1 signals during engine running SOpen or short in IGF or IGT circuit from igniter to ECM SIgnition coil No.1 (Igniter No.1) SECM P1310 No IGF signal to ECM for 4 consecutive IGT2 signals during engine running SOpen or short in IGF or IGT circuit from igniter to ECM SIgnition coil No.2 (Igniter No.2) SECM
HINT:
Ignition coil No.1 is for cylinder No.1 and No.4, and ignition coil No.2 is for cylinder No.2 and No.3

Now I only need to know where the Igniter is located
Have a great day

Pole Position
The igniter is the coil pack on top of the plug. I would look closely at the inside of the connection between the plug and coil pack. Look for corrosion. You will need a flashlight to really see what is going on. You changed the plugs, I hope you did not use bosch...They are crap. Use NGK or Denso only... they work great and last an easy 140k miles.

Thanks for the reply.
yes I used NKG iridium plugs. Your saying look into the ~5 in cylindrical tube which makes up the plug connection. Correct? Cool.
I guess I was envisioning the opposite end from where the wires that connect to the coil pack. i.e The beggining of the circuit was the problem area.
Thanks. Together we'll beat this thing!

Looking at 5 will not be easy (unless you remove the intake manifold).
#5 is closest to the driver on the firewall side. When I did my spark plugs either 3 or 5 or both were done by feel only. Maybe you can move the connector (while it is disconnected to an area where you can see it.
I would also suggest to move the coil pack of #5 to the even number cylinders [that will move a known good to #5].
Note: Most of the problems that are discussed are due to bad sensors and replacing them fixes the problem. Here it seems the sensor is good and the required debug work is needed to fix the root cause.

DTC 1300 is for cylinder No. 1. DTC
1305 is for cylinder No. 2. DTC 1310 is for cylinder No. 3. DTC 1315
is for cylinder No. 4. DTC 1320 is for cylinder No. 5. DTC 1325 is for
cylinder No. 6. Possible causes are:
* Open or short in IGF or IGT circuit.
* Faulty ignition coil/ignitor.
* Faulty ECM.
Check ignition IGT signal from Engine Control Module (ECM)
to ignition coil. If ignition IGT signal from ECM is defective,
Diagnostic Trouble Code (DTC) P1300, P1305, P1310, P1315, P1320,
P1325, P1330 or P1340 will be set in ECM memory to indicate a
specified ignitor circuit malfunction.
If ignition IGT signal is okay, substitute another ignition coil and recheck system operation. If ignition IGT signal is
defective, check wiring between ECM and ignition coil. If wiring is defective, repair wiring as necessary and
recheck system operation. If wiring is okay, substitute another ECM
and recheck system operation.

Success!
YES!!!
That did it. Removed #3 and replaced w/ known good. Also cleaned all connectors w/ spray cleaner. Moment of truth revealed no codes, fail safe is off, and the car is responsive and handles awesome in all this Michigan snow. The best news of all is I can cancel my Monday AM appointment w/ the garage.
This car sat in an auction lot for 3 months and had to be towed home. Thanks to the club and all of the great insights, it purrrs like a kitten (for now). Regardless, I couldn't be more happy and proud to have completed the job at home.
Next on the list is tranny care. It looks a little dirty I think I will just drain and fill vs flushing. THANKS AGAIN!

Yesterday I had 2 code po 300 and 1305.
I understand that 300 is a misfire but the other!
I see it's a #5 coil...is that correct? but above it's #2.
Today I changed out #5 to #2...the misfire code is gone 300
but now I have 1320 code and from above that means #5.
My conclusion is this...if I'm right using above info. I actually moved
the bad coil 1305 (#2) to #5 which then gives me 1320. If I move it
again...#5 to say #4 I should get error code 1315...correct?
Therefore I have bad coil....again! Damn it...Already changed out
2 this year..this will make 3 at $90 per
