2005 Dodge Grand Caravan
119K Miles
P0171 - System too Lean (Bank 1)
P0113 - Intake air temp, Sensor 1 circuit high input

Symptoms:
1. Car won't start easily, need to try several times to make it start
2. Idles good, no up and down rpm
3. Almost no power when you step on the gas quickly, when the speed is at around 30mph you will notice loss of power and then slowly increases speed

I recently had the dealer replace the fuel pump, I changed the spark plugs and wires as this was suggested by the dealer, but after the tune up, the van still is running without power.

Would this be a O2 sensor problem? If so, which one would it be? I hope somebody out there can point me in the right direction. Thanks!

 

Take a look at the injector harness. These codes can be from the wires shorting together.

 

Thank you Master Tech, I would need to get some help from my brother regarding wires. Will post an update once we figure this one out and hope that will help others viewing in the forum.
