0201 biggest pain in my a$$
THIS IS WHAT I FOUND IN THE STICKIES, MY POST IS BELOW THIS
0201
Diagnostic Trouble Code 0201 indicates a problem with the ignition coil and power transistor. The ignition signal from the Engine Control Module is sent to and amplified by the power transistor. The power transistor turns on and off the ignition coil primary circuit. This on-off operation induces the proper high voltage in the coil secondary circuit.
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 checked all the coilpacks with the ohm meter and they test good. I tested all the fuel inj with the ohm meter and they all test good.
This is the only code i get, no other codes follow to tell me where to head next in troubleshooting. I guess the only thing left to replace would be the CrankShaft pos sensor.
Any help would be appreciated.
Earlier i was getting rear bank running lean and then i switched the rear bank fuel inj with the front and its been 2 weeks and no running lean codes yet. So this is the only code i got left.
I got lucky because 5min after i got it smogged yesterday the friken light came on.
