Hello all right ive just got in from a long test drive after disconnecting the white wire and although the power has reduced it runs spot on no misfire no cutting out!

So would i be correct in thinking that its definetly the orps that is the problem?

thanks you all

wayne

Yeah - It's the ORPS!!

There's no guarantee that there are not OTHER problems as well - but if it won't start - then snip and now it WILL start - it's kinda obvious that the CHANGE is the signal from the ORPS!

Brilliant cheers lads i woulda been lost with out ya knowledge!

After losing my patience on waiting for call backs from isuzu dealers who dont seem to have a clue what there on about. A 60 second phone call to MILNER 4X4 has got me a genuine part being delivered tomorrow and its 50 quid cheaper!

Now i just need to follow gribbles guide to changing the little *beep*

THANKS

Its always started but when it got warm it developed a terrible misfire would cut out and idle would be really rough!

But since un plugging the white wire it runs fine a little down on power but no misfire and smooth idle

IIRC you should not drive it with the white wire disconnected

Really? i only poodled along one person on here said you will have hardly any power another said it actually drives ok so i thought a test drive will tell me if the fault is still there or not i definetly wont be taking it out till its fixed now but i really apreciate all your help.

With regards to t2 ing the sensor would a vauxhall dealer be able to help??

haha you lads are brilliant i changed my orps today with no dramas thanks to gribbles guide and now shes running spot on again so thanks lads really appreciated your help.

now with regards to tech 2 ing the sensor is it a must? will i notice a difference? will it harm the engine? My mate whos a vauxhall technician says the ecu should learn itself.

but i would rather take experienced advice from you gents if you can help?

Thanks alot. wayne
