Silverado bad tune
To anyone that has had this issue please help I own a 2004 silverado 1500 I have done the following full long tube headers, full exhaust, intake, and tune,..... Now just started last week it came up with a p0300 multiple misfire and It was a spark plug that was not screwed in all the way so I fixed that problem, but then it still had a p0171code which is running lean so I I put brand new all 4 02 sensors and no more codes, it ran good for 2 days good power then started running sluggish, and doesn't have any engine light.. When I disconnect battery for 30 min and reconnect it runs fine full power again for 3 to 4 miles then it starts with the running sluggish again los of power.... Now I'm thinking this can be the tune went bad. The truck idles fine, and no hesitation.
