My vehicle loses power while driving when it warms up but when I stomp the gas it goes back to normal for about under a minute then starts losing power again.

Hi,

That could be a few different things. It could be related to fuel pressure, a partially plugged catalytic converter, and so on. Do me a favor. I need you to check for diagnostic trouble codes. This has an OBD 1 system which doesn't require a scan tool to retrieve codes. All you will need is a small jumper wire or even a paper clip.

Here is a link that explains how to do it. If you find there are codes, let me know what they are and I'll be better able to direct you.

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

Take care and God Bless,

Joe
