I'm driving a Grand Cherokee 3.0L CRD made in 2007. From the begining I would like to let you know that english language is not my mother language, consequently some spelling issues may occur.
During a regular trip made just couple a days ago, sudenly, an engine check light flash on the dashboard together with a red light (it's about gear box related, it's like a thunder sign bordered by 2 vertical lines). I was stopped, switched off the engine, re-ignited, than the red ligh goes off but engine check still on. The car was starting running like hell, loosing power, not beeing able to go over 2000 RPM. Moreover, if I was trying for full acceleration from 1500 RPM the car replay like hell: was feeling of hammering underneath. Just driving slowly with very,very gently acceleration up to app. 2000 rpm. After couplke of KM's I was stoipped to a garage. Investigations made, but they cannot do much. They just re-set the car computer and erase the error. A computerising pressure test waqs made: this is made by 5 steps - first 4 steps were running OK, the 5-th one gave error by saying is to slow. Just FYI, I was 250 Km away from home on the way home. As the garage guys have seen, looks like it's about a flow valve from high pressure pump nor 1 of 6 injectors. The garage guys were saying also that could be an injector re-tour issue which is given a troubleshooting to the flow valve. I'm not sure, is just a supposition as looks like some deep investigations are in need.
Did anyone else met this kind of trouble? If yes, may I have an advise from you?

The light should be out.

Found what I think is the ccv pipe was loose, so got it seated back as best as I could (it was a bank holiday weekend so nowhere ope to get a replacement) and the light went out and the truck run fine for a few days, then after a short trip out the engine was lumpy on startup and when driven, got home and the ETC light started flashing again. If I stop and restart the engine the light doesn't flash but if I rev the engine to 3000-4000 rpm for a short while the light starts flashing again. Could this loose pipe be anything to do with it or am I looking at something far less simple?

Thanks guys!
