Omega General Help / Re: Multi Ram Check?

« on: 26 July 2011, 09:14:05 »

hallo to all.

the multi ram valve on the back of inlet manifold should open on 4100rpm, while other one near radiator opens on 3500rpm.
i have a problem with that on the inlet manifold, it shows no signs of working. it shoud work on idle speed and on 4100rpm as i said. the valve is working when i take off The throttle position sesnor (TPS) and i turn it with my finger, then valve opens, but when i put it back on throttle body, valve is not working again.. could someone explain that strange situation? please help.

but this revs jumping is just when working on LPG. on petrol there are no sympthoms of Idle control valve working bad. So if can be so stong difference between petrol and LPG because of oxygen sensors? one of them is NGK universal o2 sensor, other is Bosch (3wires). vibration is all the time, on petrol and on LPG.
i don't know what to do, i'm tired of this...

no, just codes: 136 and 31(it is normal). also i tried to swich maf sensors, but there was no change. And electrical testing of multi-plug pins showed good working results, as in Autodata required.

just 136 fault came up. what does it means? also maybe these problems can be because of automatic gearbox faults? when i checked it result were: to replace change TPS sensor( but i don't know if that can solve everything), also some other faults about ignition/injection cutoff valve no signal and low or high voltage (i don't remember, maybe 84 or 89 fault)

also i have to say that i have changed the engine from vectra to my omega (with metal cover gaskets), but all sensors and electrical maintenance i left from ex-engine. in the begining work was great, but after half of the year began to work noisy, also fells big vibration of engine, and there are not many torque left, from 170PS it seems that left just about 120PS. Also one of the intake solenoids valve not working (upper).

my V6 is working not propertly, here is the video: http://www.youtube.com/watch?v=WGYVZyFhuUA

i don't know what can i do, i can all car electrical parts change but have no results, i am jus guessing what could be the reason of working like this.. Crankshaft sensor? TPS sensor? ignition coil?
