1992 Chevy Lumina subframe Bolt

Hi:
Without seeing the subframe problem, I can't make any recommendations. If you can take a few pictures and upload the for me, I may be able to help you.

As far as the running issues, it sounds like a fuel pump or filter problem.

Have you had the car checked for trouble codes? If not, take it to an nationally recognized parts store like Auto Zone and have them scan it. Most of these stores will scan if for free.

The reason for this is because there are several things that could cause your problem, and I don't want you to start throwing money into things that don't need repaired.

Let me know what you find.

Joe
