Friend of mine has a 1998 Opel Vectra B with Automatic Trans and a X18XE-Engine.
Sometimes it runs fine, and sometimes it doesn ´t want to start or only with
foot on the Gas, and then it stumbles and pops like backfiring trough the Intake.
In all bad running cases it sets a P0335, and now and the a P0130.
He was at the Dealer so often ,they know him by name
In advice form them :
He already changed the CAM-Sensor (3 times) , the CRK-Sensor (2 times), the Engine ECU (2 times),
he took apart the timing belt and allined it (2 times), he removed almost the complete
Engine wiring and measured the Pins from ECU > all reachable Sensors and Actors with a DVOM,
replaced the Battery now the second time since he has the Car.
And last week 3 days o.k, and before the Weekend, it kicked him again with the P0335
and didn´t want to start and run.
While testing he came across one thing that won´t get into my head, he told me that he had the
car idleing (bad) and then disconnected the CAM "and" the CRK , and the car just stumbled on
like before....HOW could that be ? I was thinking of , could it run off some RPM-Input from the
Automatic Trans ?? And could this be maybe the cause of his whole problems ?
I will go there when i get time, but before that i researched a lot and would like to ask if someone
has a CAM/CRK Picture for this Engine ? I read that the CAM Sensor is a very strange thing
that uses "Phase-Shift" signals - how do i get a good Waveform of this Sensor in comb with the CRK.
Information about it is hard to find.And before driving one hour to him and then get back with
bad or no useful Waveforms would be wasted time.
Any Information is welcome
