While accelerating to highway speeds it stalled out. Now has rough lumpy idle and won't go over 1,000 RPMs.

Hi,

Were there any strange sounds or smells when this happened? This could be several different things causing this. For example, a failed fuel pump, camshaft or crankshaft position sensor issue, a plugged catalytic converter, and so on.

What I suggest is this. The first thing that should be done is to scan the computer for diagnostic trouble codes. This should point us in the right direction.

Here is a quick video showing what needs to be done. I realize most people don't own a scan tool, but often times a parts store will lend one to you.

Do this and let me know the results. I will watch for your reply.

Take care and God Bless,

Joe
