Coil Packs Question
Ok, I have at least one coil pack that has gone bad. What I'm curious about is has anyone ever taken one apart, and tried to fix it. My code is P1320 which tells me to replace them all, but da** at $70-90 bucks apiece, I would prefer to somehow fix mine.

I checked the stickies first, but was unable to locate it. The OBD II scan has two codes, but both are P1320, does that mean two coil packs are bad? Or am I possibly facing some other problem?

P1320: Ignition signal Primary circuit fault.
Note: The ignition signal from the ECM is sent to and amplified by the power transistor. The power transistor turns on and off the ignition coil primary ciruit. This on-off operation induces the proper high voltage in the coil sencondary ciruit.
Things that can cause this are as follows:
- Harness or connectors
( The ignition primary circuit is open or shorted)
- Power transitor unit built into ignition coil
- Condenser
- Crankshaft position sensor
- Crankshaft position sensor circuit
* Unfortunatly '99 are known for this, It disturbes me because I also am a '99 owner. Good Luck

The malfunction is detected when the ignition signal in the primary circuit is not entered during engine cranking or running.
The items to check include
- Harness or connectors (the ignition primary circuit is open or shorted.)
- Power transistor unit built into ignition coil
- Condenser
- Crankshaft Position Sensor (REF)
- Crankshaft Position Sensor (REF) circuit
A misfire on any individual cylinder should set a code, and a problem with the CPS should also set a code.
I would have expected to see DTC 0201 along with one of the following DTCs.
0407 - Crankshaft Position Sensor (REF)
0608 - Cylinder 1 misfire
0607 - Cylinder 2 misfire
0606 - Cylinder 3 misfire
0605 - Cylinder 4 misfire
0604 - Cylinder 5 misfire
0603 - Cylinder 6 misfire
You didn't get one of these "companion" DTCs, and that is puzzling. Maybe one of them will show up in the next few days.

I have 99 I30t which is giving a code of 1320 from my new (from ebay) OBDII scanner. For $30 it gave the codes and reset the CEL nicely.
According to the Code sticky and haynes, this translates to a CEL code of 0201. The info for the 0201 code suggests that you (and I) should have additional codes as well, such as a cylinder missfire. If we don't, does this still mean we need to replace the coil packs or is it something else?
Based on all this, I guess the recommended solution is to replace all six coil packs. Is this really necessary? Haynes gives a method of checking the coil packs to see which one is bad. Would it make sense to only replace the bad one if it can be identified? (making this a $50-60 repair instead of a $300-400 repair)
I guess I would like to know why everyone replaces all 6 coil packs instead of just the bad one.
Thanks! Any additional thoughts would be welcome.
