If the plug was the right type, then it was the right sensor.

All my Omegas have been 1998 or later, and have had Bosch sensors, hence I thought they were Bosch.

Two sensors , different Bosch/Siemens , same mounting same multiplug , ?? Why do they do that , checked again with vauxhall today and the epc states the car needs the supplied siemens sensor.
Glad of all the help. Ignored the parts guy and brought the Bosch sensor that I was told would not work on my car, well how wrong was he. And it was nearly half the price.
110 miles this evening and fingers crossed the problem is behind me.

So do I try the Bosch sensor in a 1997 car , cause the siemens sensor is not good , changed twice , no improvement and only fault code 19.

Thanks for the link rob , sounds like I need to try a Bosch sensor tommorrow. The text seems to indicate though , bieng an early car it's likely to be Siemens from new anyhow?
Got to be worth a try , nothing to loose.

 Hello,
 Not posted for a while but really could do with some help and advise. I will say where I have got to and hopefully someone can pass on some help and experience.thanks.

 The car , a 1997 76k 2.5 24v  manual omega , with prinz LPG, new coil pack , leads , plugs.
The car has previously run well without fault . The car stalls and the revs fluctuate at idle when hot prior to stalling. When cold it seems good , but when its hot the stalling is very regular the fuel choice of petrol or LPG makes no difference what so ever , so not fuel related. Scanning the car brings up fault code 19, crank position sensor.
Have replaced it , then again , twice in one week , the sensor fitted is genuine and is also marked Siemens. The fault remains. Checking the car car on live data the scanner receives a rpm signal from the sensor. Live data also shows the maf , air temp , coolant temp , cam ,maf, o2's and iacv all showing sensible readings. Really at a loss as what to do next , guessing it could be crank sensor wiring , is there another connection I can check , anyone had the same issue?.
Many thanks

Tonight it stayed on and lunchtime it went off 3 times in 2 miles :-?

Omega General Help / Engine misfire on l.p.g only

« on: 14 December 2009, 00:18:29 »

Hello, just joined the forum tonight and wondered if anyone has experience of the problem i am having and is able to offer any guidence thanks... A couple of months ago i brought a 1997 `R reg 2.5 v6 omega reflection which had only had one owner from new and 40k . After driving the car for a few months and enjoying trouble free motoring i had an opertunity to swap a fully functional prinz lpg conversion of a friends 98`s reg 2.5 cdx which he was saying goodbye to on the scrappage scheme,so along with the full leather interior, i swapped the conversion over. On petrol the car runs fine. however on lpg the car is ok, maybe very slightly lumpy at tick over and if you don`t load the engine and rev it gentley it will rise through the rev range smoothly, likewise whilst driving at a set speed on the flat you can swap to gas and make smooth progress for miles.the problem comes when it is revved hard stationary or is accellerated on the road whilst on lpg, even very gentle accelleration and it misfires awfull , swap back to petrol for an immediate cure. Firstly thinking lpg would need a stronger spark i have replaced the plugs with twin electrode ngk as recommended they came out clean and oil free and a set of delco ht leads,(and a new egr gasket after breaking the old one!),no difference what so ever!   .today we did a non stop 90 miles and when pulling away from a motorway roundabout i thought i had a lumpy moment on petrol but the kids were chatting and the cd on so can not be 100%.but it was making me think of prehaps a dis coil pack with cracked ceramic??.the car is manual and the engine vibe through the gearstick on lpg is so obvious and on petrol is non excistant. i can not afford to through loads of money at the car as the gas kit came f.o.c and i feel very lucky to get it but i have already spent out on plugs and leads i havent needed so will the dis oil pack be likely to be further wasted funds , could it be anything else? the mil light does not come on and the prinz lpg was extremely smooth on the other omega prior to removal. the gas tank was low so i have put a further 20 litres in just in case it was some kind of pressure issue..thanks for reading through hope you can help   andy
