It sounds like it going to shut off it was going 70 mph. Now i'm lucky to go 15 mph. I bought the car two months ago they said it just got its fuel injectors replaced.

Hi,

If you are experiencing a power loss, it can be a few different things. A plugged catalytic converter, low fuel pressure, ignition related issues and so on.

Here is what I need you to do. This vehicle has an OBD1 diagnostic system. You don't need a scan tool to get codes, so we need to check if there are any that can point us in the right direction.

Here is a link that explains how it's done. All you need is a short jumper wire or even a paper clip.
