I have a 2004 chevrolet silverado 1500 5.3 liter automatic. The check engine light came on and the truck engine started to idle rough like it wanted to die but didnt. It not only does this in gear but also in park. I had 3 different diagnostic test done only to recieve multiple codes of things that could be the problem, such as, oxygen sensor, lean fuel, engine vacume leak or misfire, low fuel pressure, power train module, computor has recognized a rich or lean condition on the left bank only probable cause, mass air flow sensor. Those are from Auto Zone diognostic reading. Car MD diognostic readings are anywhere from plugs n wires wich ive allready replaced to intake manifold gaskets, crankshaft positioning sensor. Since this problem ive noticed a drop in power and fuel economy. Can anyone help me out to better pinpoint the problem with out replacing a bunch of parts that dont need to be replaced? P.S. The truck has aaproximatley 122,000 miles on it.
have the same problem?
