    Default 1996 GMC Sonoma, 2.2L/ 5 speed, rough idle!!!!

    I have a 96 sonoma I recently got to cut back on gas, It has a very bad idle, almost like a miss while idling, but is smooth and runs fine when driving. I have replaced wires, plugs, and both coil packs and one injector, this helped a little but still bad, and vacuum hoses seem to be good, it has some wire damage from a rat from sitting up, I have repaired most of that, but any help would be appreciated.

    Thank you

    Welcome to the G M T C ! Have you taken it to see if any "codes" come up when scanned? Around here, the "Auto Zone" parts stores will do scan for bad parts.
