Acts like it's cold natured. It runs great as long as idling as soon as I put in gear it starts stalling. Running sluggish.

Hi,

There is a chance the fuel pressure is low. Have you checked pressure? If not, that should be done.

Here is a link that explains how it is done:

Also, follow the directions in the following link to see if there are any diagnostic trouble codes stored that may point us in the right direction.

Let me know what you find. Additionally, let me know if this only happens when the engine is cold.

Take care,

Joe

Doesn't matter how long it's been running it does the same. I bought it recently and don't know much work has been done.

Hi,

It could be a few things. Start by checking to see if there are codes stored that may point us in the right direction. It is likely something simple.

Let me know what you find.

Take care,
