hello all,new to this board,first post.have any of you had the faulty gas guage where it usually stays pegged on full but everyonce and a while it moves to half or a quarter but goes back to full.i have a 97 astro with 124xxx miles.ive had it for 3 weeks now and plan on eventually changing the fuel pump anyway just for peace of mind.just wondering if it was a common problem/fix besides changing the sending unit.btw,this is my third stro,first was a 99 then i had a 96,now a 97.all coincidentally white.
