Question about 2004 Chevrolet Silverado 1500 Crew Cab
This can be a number of things. Could have any of the following.
Bad fuel pressure either by a bad pump, bad fuel pressure regulator, bad injector
bad ignition coil pack
broken spark plug seems stupid but you only have to crack it just a hair and you will have a misfire
bad mass air flow sensor just unplug it and see if your idol returns
bad egr valve or sensor
bad idol air control sensor
If you have not checked for stored codes then you may want to consider doing it. That will at least eliminate several of the items.
