I have a 1991 1 ton 454 , i am getting codes 43, 44, 85, it backfires some times and seems to have lost power, seems if i dont put my foot into it goes ok,when i put my foot into it it just sucks air and does not seem like it goes anywhere, engine idles smooth as silk.

Cheers

James

  maybe when the trip is over, check all the other joints in the front end, like all the ball joints, tie rods, pitman & idler arms, etc...

  Thks, and actually it was my bad, because here in this post there is someone showing the correct wire position as well. My bad... But thank you a lot with the help as well. I was able to find and buy a 10 channel VPM that came from a sister silverado of mine. The same year, same mode, same trim, same everything. 2022 Silverado 1500 LTD LTZ (pre-refresh). I also found to buy just the bottom mirror part that has the cameras, so way cheap than the full mirror. + a used front camera. I did test everything together, cameras, cables and the VPM.... everything worked EXCEPT my original Bed camera and the backup grid lines. I think the reason is because now I need to do the VPM reprogram. I sent a msg White Automotive & Media Service to confirm that it is the problem and that they can do it service for me case. Once I get it 100% done I will post here result....

  I used to work on those 4.6, 2V engines. They are tough.

  Nice! I wish I had something to put them on. Someday when the engine craps out in our '86 Grand Marquis I guess. My truck is diesel, so won't need one for that. The Merc is at 315k miles right now with zero signs of slowing down! I'm more of an Edelbrock guy, though. I like super-simple.
