It runs good for 40 minutes then seems to bog and only get up to 40 MPH slowly. Idles rough as well.

Hi,

This could be a few different things. The first thing I suggest is to check for diagnostic trouble codes. This vehicle has an OBD1 system. It doesn't require a scan tool to check for codes. All you will need is a short jumper wire or even a paper clip.

Follow this link and let me know what codes you find:

Let me know what you find or if you have other questions.

Take care and God Bless,

Joe
