Okay great thank you .

No codes ? Normally we find when this happens it a fuel issue, i would first try a good fuel injector cleaner which will clean out the injector pump and injectors .

Worst cases scenario was a problem with the injection pump .

check and replace the fuel filter .

In Most cases a fault that has no malfunction codes is fuel related .so start there first .

Fuel pressure sensor also a common issue when you are under a heavy load (Hill clime) fuel

pressure is not enough or fuel pressure sensor is bad and will cause the check injection comes on .

And may not trip a code .
