We have a Dodge Ram 1500 5.2 L. we are having problems with it running, its keeps showing that it has a lean on bank one. we replaced the o2 sensors and replaced the fuel injector and spark plugs. We put the truck in gear and it will not stay running, it acts like its getting too much fuel. It spits through the throttle body. Was wanting to know if it was the timing chain.

 

What year truck?

Any other codes?

 

timing chain is a good bet . check wires , plugs etc as well .
