I thought the P0202 code was the PCM, so I ordered a new unit. Fired up the truck and still feel the lumpy misfire and code P0202 popped up again.

I have read other threads and swapped the injector to another and its still #2 P0202. I have read it could be the grounds. Anyone have a picture of where they attach on the engine? Did a search on google to no avail.

Anything else I should check.

THhnks for any help.

 

I found a site that has the grounds for the 4.7 and mine were not on correctly, but still didnt change the P0202 code.

I attached the grounds where they should be on the coils per the link above and no luck.

The ohms on the injector #2 are 12.6. I have a mechanic stethoscope to listen and I can hear the injector fire, clicking over and over. I checked the sound with #1 injector and they sound the same (sound though really means nothing).

When the engine was running I pulled the injector plug on #2 and nothing changed in the cars lumpy/misfire idle.

Never been more stumped with a car than this one.
