fitted the mantzel now so quite happy i till i drove it, first it was cutting out at 5K RPM
ECU fault code 68
Air Flow Sensor (AFS), hot wire meter (air mass meter) Faulty air mass meter signal, incorrect frequency.
then i checked the airflow meter, all ok, reset the ecu and then let it idle for a while then revved up to 6.5 K RPM then dies
ECU Faultcodes
24,25,81,92 
Injector valve - High voltage
Camshaft sensor - Faulty hall effect sensor or circuit
Vehicle Speed Sensor (VSS) - No speed signal or low voltage
Injector valve - Low voltage
i think the VSS one is becouse the speed cable snapped
any one be albe to shed some light on this.
thank you

Might be a silly question but when you fired it up without the box on jsut standard did you get those faults ? Also i dont think you can reset ecu's without a diog, i think its a myth personally.

that garden hose brake servo pipe will collapse you know

the garden hose is tempory  will that cause the faults do you know.
the car was perect before the new maniflod was fitted.
and yes the ecu was resetted with out the diagnostics tool

i wouldnt worry to much as you onyl have 2 problems really VSS will be because of the cable snapping, Injector valve low and high voltage so sounds a bit fubbared, camshaft sensor if i remember correctly my mate had this and cleaned the end of it with some fine sand paper and its been fine ever since

thanks rob,
when i did the first Paper clip test it read a fault, then i disconected the battery and tested again and it was clear, so going by that i'm thinking that it resets.
not worried about the VSS as we know but the injectors, any one know how to solve this.
maybe put my old injectors back in from my C16?

Yeah well personally seen as you have those to play with i would put them back in and try them cause you never know about differnce in tiny things like that..

yer i know what ya mean, gonna do that tomorrow.
do they just pull out or screwed in do you know? the injectors that is.
92 sensor error gone since i clean some greas of the cam sensor  cheers rob.

That isnt a mantzel its one of those so called copys. I see you have the problem where the pipes are in the way of the header tank.
Also what pipe have you used between the airflow meter and the throttle body as they are different diameters. Are you running with std airbox or induction kit?

injector voltage low etc is basically because of a poor switched earth.make sure the earth on injection rail area is not loose as the ecu sends a pulse which needs earth from injection loom to pulse injectors. if speedo cable snapped that will cause vss code. will show camshaft if car has cut out because the ecu still receives vehicle speed pule without a crank rotation pulse so it thinks crankshaft sensor dodgy.

thanks peeps
Ainsly, the adapter is one i soureced from rally site, the diameters are different and the correct size, i fixed the fitting and did another ecu diag and that code 68 airflow sensor error did not reapper so thats ok.
Bubble:
sounds like you on the ball, not too sure on the earthing point for the injector rail is, i'm thinking it's on the inlet manifold 
i do remember an earthing point on the inlet manifold and i'm sure that is secure.
i know it' deffinatly earthed where the alternator is mounted, is that not it

Injector valve - High voltage
Vehicle Speed Sensor (VSS) - No speed
Injector valve - Low voltage
just got these faults now.
do have a pic of where the injector rail earth is if possibel.
thanks bubble.

Will wipe off the VSS because you know that is because of the speedo cable so the only fault youve got is the Injector Valve
Can i ask how long you removed your Positive on the battery to reset the fault codes on the ecu ..

injectors all worked fine when i took em off mine mate, did have a seemingly unsolvable running problem though, suppose an injector may have been at fault but like rob says, check them earths

yer VSS can be removed was not meant to put that up.
removed it for about 5 mins.
yer i might change the injectors for my old one.
where the erthing point for the injectors?
is it not on the manifold? or is it on the rail itself?
gonna check it tonight.

IIRC its around the injection loom area, basically just a little 10mm round earth, but its triggered via engine ecu, so if this earth is not on, then u will deffo get injector voltage high or low code.

The earth was bolted to a bracket near the throttle body mate, I just put it onto one of the bolts for the egr blanking plate on mine, not had any problems with it cutting out or anything.
My engine warning light comes on after giving the car a thrash then slowing down, stays on til you re start the car. Have read it may be the EGR valve hitting the blanking plate but haven't had time to check yet!!
Did you have to 'modify' the firewall/bulkhead to make it fit???
Heres my post about it on JOV http://www.justopelvauxhall.com/forum/viewtopic.php?t=1469

Did you have to plug the EGR valve back in or not?
what do you reckon of the performance since fitting it????

in the middle of changing the injectors to see if it removes the fault, what a pig they are
have also put proper vacum piping on the servo pipe.
thanks bubble.
i have an earth on the inlet manifold and also an earth straght from the battery onto the EGR blanking plate.
I'm gonna change them to see if this works.
put the battery one on the manifold and the other on the injector rail where it secures to the manifold.
I did have to modify the bulk head by tapping it back to fit the throttle body.
the EGR is not connected as mine is a C16XE and they never had them so it's not wired up.
have not noticed the performance yet really as it has been kicking up ECU errors and bums out at 5K RPM.
Thank you all, gonna update you tomorrow evening.

i've marked all my earths in red
earth from loom
can you see anything wrong?
earth from loom
earth from battery
I might put the erthing point from the loom on here to see if that resolves it.

earthing points look ok to me... swapped injectors yet? also check the fook off great big round plug that connects injector loom to the main loom

I used to get the injector fault pop up when i had a Mantzel on my C16XE, it used to ping up the ECU light when caning it, i was racing Broster back from Milton Keynes Cruise one night and bounced off the 7800Rpm limiter and it came on and carried on to do so randomly from then on. I just assumed the injectors were working overtime as i swapped them and the fault still remained never manage to get rid of it but one thing was sure it was running WELL rich
