Possible Misfire & Stalling while driving
Good Afternoon,
I have a 1999 silverado 1500 4.8 single cab.
I started having the following issue after the transmission was rebuilt.
as im driving and I step on the gas the engine stalls for about 3 to 4 seconds. when it stalls I tried pressing the gas and there is no response from the truck until it kicks in on its own.
I took the truck back to the transmission shop and they are telling me its not the transmission.
i ran the codes and the only code showing up is the p0420 because when i bought the truck it had no catalytic converters. I recently replaced the upstream o2 sensors bank 1 and bank 2.
I uploaded 2 videos on YouTube
