Scott and Dennis - Thank you for the additional suggestions. I didn't get to this yesterday because of other commitments. The symptoms worsened on my ride home yesterday. To the point I selected an alternate route home because I was barely able to keep it at 40mph. I will test the fuel pressure and see if disconnecting the O2 sensor does anything. The Temp II sensor is fairly new but I will mess with that and check the grounds at the engine while I am at it. I do have another fuel pump I can swap in and will pout a new fuel filter in as well. I also have access to an AFM I can try as well. Dennis - it is definitely and "under load" situation as it starts and idles perfectly fine. No backfiring (yet).
Thanks, Jeff '85 GL (Gertie) '78 Bus (Melissa) Patty's Bus |
