we spent the day on measuring the things one by one. I took the Jeep there and exchanged the parts one by one, but nothing helped.
Checked the coils, changed the injectors, checked the wiring from the PCM to the coils and to the injectors.
In the afternoon a guy brought a Bosch application that sw has a Chrysler 300c profile. It said everything is all right. With an oscilloscope they measured the camshaft+crankshaft+Injector1 signals and they said it will be not the timing chain, the fireing order is right and in time.
The only thing they will check tomorrow to remove the exhaust , maybe the catalisator is dirty or broken. But we have no other idea...
I could move the car from a building to another, max 150 meters, but the car really feels bad.
I also have an LPG system in the car, but i used it for 2 years without problem, and that was the firs we disconnected, so now it is switched off.
i recorded a video, maybe this helps a bit more
One more thing that was interesting: we checked the sparks again today, an the sparks in the cylinder 1 and 6 look wet more than the others. all the others are brown but these were like overfueled. but the coils the injectors were exchanged and we couldt really figure out what can make only those to wet
Any idea is appreciated since we do not have anything to continue with.
