Customer Question

working on a 2003 dodge ran 4.7 engine. error code p0172. I've replaced both 02 sensors, all injectors, air temp sensor, new plugs, new air filter. Local shop could not fix, told me he felt that it might be ecm. I've checked all vacuum lines, replaced any that looked worn. I've inspected all wiring on injectors and modules, looked good. Is ther any thing else I need to check.

Does the code come right back after you clear it? Is the engine running rough?
