T180, the engine light is on, but sometimes it goes off, and sometimes at about 2000 to 2400 revs it looses power and goes in to limp mode but just for 10 to 20 seconds then kicks in again and is fine, can you please help, cheers,
martin.

We need to start with checking the codes to find out what the module is seeing that is forcing it into limp mode.

Here is a guide that will help with this:

Also, I am going to attach the common causes of low power in this guide which will help with getting us started:

This sounds like a sensor issue so I would suggest we start with checking the codes because I suspect you will find a lean code. If you do, here is a guide that we need to jump to.

This could be a vacuum leak as this talks about so let's check the codes and go from there.
