So far on Factory Engine.1- On 6 th speed will start shaking, had to change to 5 speed. 2- Rocks on stopping . 3- Codes P0300 on two. P2308 on two. P0306 C 6 misfire. 4- Checked , Spark plugs, Coils, all good, BUT ,NO Spark on plug # 6. Checked Ignition Pack No spark on # 6. Checked with light tester , ON. Switched first the coil with 1 & 6 , still No spark on either Ignition Pack Nor Spark # 6. I replaced the Ignition Pack .. Nothing changed. So I returned it back. For money I don't have in first place. I'm still driving it Kids to school. . Drive rugh and getting worse, dies if Idle on Neutral. Ok if Idle on D. I Googled for PCM and ECM , to see if I could do something , No success . money is little tight , Pleeeeease Need hands on Help. For something I could do myself. Thanks in advance. I hope itsnt the motor !!!

 

" Checked Ignition Pack No spark on # 6. Checked with light tester , ON."

I'm more familiar with earlier model vans so can't be sure but if this statement means you checked the coil driver pulse from the PCM at #6 coil and the test light stayed on steady then it should mean you have a PCM problem. It should blink as the engine rotates.
