Name is Greg, My goal is to provide you with excellent service – if you feel you have gotten anything less, please reply back,

Is the check engine light ON when the engine is running .

If it is you will have to get a code reader to check for malfunction codes .

If not do the following to see if this is a hard code or soft .

Disconnect the battery ,make sure it is fully charged , then reconnect ,this will clear the management system of any malfunction codes if soft , then try and start then accelerate ,

If the battery is to low on voltage then you may have this issue .

What ever cause this to happen is one of the sensors have failed and but your engine in
safe mode ,

Let me know what happens for further assistance so we can continue .

Hi .

Frank great you have a code reader do this first before removing the battery or you will lose any stored codes .

If you have a spanner that is light up this is just the maintenance indicator .

But check codes first then charge the battery .
