Motor wont go past 2000 rpm truck will move and be driven just wont speed up
Since you didn't say what engine you have, I am assuming it to be a 3.7 L. Code P2305 is set for insufficient ionization of the #2 coil.
1. Inspect the spark plugs for correct application, these should have NGK platinum spark plugs installed. Inspect the plugs for any signs of misfiring, such as carbon tracking on the spark plug insulator or the coil boot. Inspect for cracked spark plugs or incorrect gap. Inspect for any kind of fouling on the spark plugs. Replace the spark plugs or the coils as needed.
2. Verify the wiring is not shorted to ground from the coils to the Powertrain Control Module (PCM).
3. Keep in mind that anything that can affect the air fuel mixture can cause this code to set. Be SURE that there are NO vacuum leaks, the injector is not at fault, etc. Moving parts one at a time (spark plug; coil; injector) to "known good" cylinders is the best way to diagnose this trouble code.
It is in limp home mode , repair code P2305 and reset computer

It means that it didn't receive a signal from the transmision module.
Have your transmission control module checked.
To reset your engine codes:
Remove the negative terminal of your battery (10mm wrench).
Turn your ignition key to START and hold it there for about 15 seconds.
Turn your ignition key to OFF and remove it.
Connect the negative terminal of your battery.

below is coped directly from Chrysler. sorry but if you have that code you need a PCM
Symptom:
P0601-PCM INTERNAL CONTROLLER FAILURE
POSSIBLE CAUSES
POWERTRAIN CONTROL MODULE
TEST ACTION APPLICABILITY
1 NOTE: This DTC indicates an internal PCM problem.
If there are no possible causes remaining, view repair.
All
Repair
Replace and program the Powertrain Control Module in accordance
with the Service Information.
Perform POWERTRAIN VERIFICATION TEST VER - 2.

It may have a "loss of prime" code that usually follows a service of the fluid and filter. After you're sure the fluid is full at operating temperature, disconnect the battery for a few minutes and reconnect to see if the code resets. I hope this helps.
SOURCE: cylinder 1 misfire
If it smooths out at wide open throttle it's probably not the injector but rather a substantial vacuum leak at that cylinder.
