Emissions Test With Stage One

I swapped the stock PCM back into my 2003 and left the S1 injectors in place. I drove the car about 300-350 miles before the OBDII plug-in test (engine was not started). The car passed. I drove the car another 400-500 miles with the stock PCM. At that point I started getting mid to high rpm hesitation/miss and discovered that the plugs were fouled. I changed plugs to the NGK V-Power LZTR5A-13, stock number 4306. These fouled, too. I finally reinstalled the S1 PCM and cleaned the plugs. I haven't had any problems since switching back to the S1 PCM.

Great to hear that it passed the OBDII test with the stock PCM and the Stage 1 injectors. My biggest frustration with swapping PCM's for the test would be the transmission relearn since I have the autostick.

I hate the continued silence on the part of Chrysler after we heard that they were going to try to get Stage II CARB certified. I have been waiting for that to solve the problem.

I posed the question about having to redo the tranny quicklearn to brngrhd, a master DCX tranny tech, and he said there was no need to do so under the circumstances you mention (swapping S1 PCM for stock and back again)

Nice to know you can swap the stock PCM for OBDII testing and get it out again before screwing up the plugs.
