my jeep wrangler's acting up a bit. 
89 2.5L 4 cylinder, 5 speed manual, 4x4, no a/c.
this morning on the way in to work, she started acting up a lil. headlights flashing, radio won't stay tuned, etc. 
 i took a look at basics, and thought i had it, as she was near perfect on the way home...then it started again.
 i figure it has to be a bad ground, or something shorting. gonna pull her in the bay tomorrow and find it. 
 have any of you guys had this type of problem? what i mean, is there a common problem like this with the older wranglers? this is my first one, and i've not worked on many. 
 thanks doods@!!
