  1. Right. But the only codes showing up are for the o2 sensors. It will hit around 5000 remember not sure on exactly how hi but it feels like it's got tons of power.. I'm stumped. Sent from my SM-T550 using Tapatalk
  2. I have a 2001 silverado 5.3 4x4. 195,000 mi. Recently replaced fuel pump. At wot it will not transition into next gear unless you let of fuel. I've taken to transmission shop and had scanned. Showed no issues with transmission but excessive back pressure. They said it probably had a plugged up cat. So I removed cats and I still have issues. I've changed plugs and wires in case of fouling. No luck. Any help out there. Please. And thanks in advance. Sent from my SM-T550 using Tapatalk
