2001 Grand Cherokee, running rough
I let my jeep sit for about a month and a half. Engine ran mostly fine prior to parking it, occasionally a bit of a rough start but nothing like this. Now it will start, but runs rough as if not firing all cylinders. It won't rev above 2000rpms, or get over 15-20mph. Probably unrelated, but the volt meter in dash isn't registering at all now, even though battery is charged. Not sure where to start as I am new to the jeep world! More used to working on my jetta TDI. Thanks for any input!
