Welcome. It sounds like you might be experiencing the 2mph fuel cut. I believe that this was programmed into early cars as part of a recall regarding the steering column locking. If I remember correctly, the car was programmed to cut the fuel if it thought the steering column lock malfunctioned. If you google "2mph fuel cut" and "column lock bypass" you will find a lot on reading.

In the meantime, in preparation for the people who will come along who have worked with this issue. Are you getting any messages on the dash such as pull key and wait 10 seconds, or any other messages? All of this info will be helpful. I would suggest pulling the codes and having them ready. Here is a link to a quick video to show you how to do it.

If you do install the LMC5, be sure to do the brown wire mod (instruction included). Some cars still have the message after installing the LMC5.

C5Diag - I have sent you a PM. Monica has had the LMC5 installed, but being in Sweden is having a problem finding a competent tech to diagnose. Can you read my PM and respond in PM? Thank you, Ed
