Vehicle: 2003 Dodge Ram 1500 SLT
94,000 miles engine 5.9 liter
Maintenance: Had engine light on and it threw this code, so I had a complete tune up done....plugs wires cap and rotor. Drove a block away and the light came back on. Took the truck back and they cleaned the throttle body and fuel injectors. Drove approx. 10 miles and the light came back on. Can anyone tell me what else would make the computer throw this code. All the parts are new and it idles like crap but smooths out a bit on acceleration. If anyone can give me some insite on this issue it would be greatly appreciated.
