Ive got a 2005 silverado that has me stumped. The truck has been stumbling on accelaration. But runs fine at wide open throttle. It just seems to hesitate when it is in the 2000 to 3000 rpm. I pulled the plugs today, and they are all white. Replaced plugs and wires today.
Pulled the codes today and coded lean bank 1 and and bank 2.
Any ideas what is wrong
