Im stumped and wish for some help.

did you ever figure it out? Some common problems are clogged cattilitic converts, clogged fuel filters, faulty fuel pumps that run only part of the time. If you respond, maybe we can trouble shoot your problem.

Can someone help me with my 92 LeMans? It used to run pretty good IF i kept it above a half tank of gas. Not sure what that means. Now it is hard to start but once started will run good for about 10 minutes then start chugging. It will keep running as long as I keep pumping on the pedal (sometimes). Its like not enough fuel is getting in there or something. Any ideas. If I let it sit for a few hours it will start right up again but do the same thing over again. WHen i pump on pedal to keep it running, is this dangerous? Wondering if this is something expensive?????
