Title: AGU engine Help plz
Post by: inggti on 22 April 2012, 15:40
Nice yesterday my agu has been holding bak and then going then it will cut out but start after a few seconds. I plug it into snap on machine and all it said was temp sensor and battery had died. I've changed spark plugs and rocker gasket cause there was bit of oil round spark plug. And now had second hand coil paks. But still hesitating. And wen u foot it to the floor it's like a kangaroo. Only thing is I did run it really low on petrol last white notch past red. Plz plz any help

Dont like the sound of second hand coils! Would have thought you would have a misfire code if that was the cause.

Change temp sender, easy and cheap.

I would usually say boost/vac leaks, but you would have thought you would log a code, can you pressure test it?

I'll change Ensor tomorrow and no other codes. And air got the stuff to leak test. It's only been like it since yesterday. Really wen it gets upto temp. From cold it's okay

being an AGU my gut says ignition amp, but a dying fuel pump can cause similar behaviour.

Drained battery and misfires?

Check your earth leads. Specifically the one from under the battery to the side of the block.

Probably not that, as you'd get a short to ground fault. But it's free and easy to do.

Post by: inggti on 23 April 2012, 20:51
Yeah drained battery and now miss fires but not for first few minutes of driving but then holds bak and missfires

can you restart it right away or do you have to wait for it to cool down?
Title: Re: Help plz
Post by: inggti on 26 April 2012, 22:17
It starts straight away well a few seconds of holding the key. Some times a bit of accelerator pedal
Title: Re: Help plz
Post by: topher on 26 April 2012, 22:20
don't suppose that temp sender code popped back up yet?
Title: Re: Help plz
Post by: inggti on 01 May 2012, 22:45
No it hasn't. Still the same. I ran out of petrol earlier. And I now it wouldn't start straight away. But it sounded as if it wasn't firing. My mate said change the crank sensor?? I now wot it is but could this b the cause of my problem
Title: Re: Help plz
Post by: cullygti on 01 May 2012, 22:54
my old engine used to do this mate and one night was sat waiting for over an hour before it would restart but as i seized the engine i never got to find out what it was am still curious now as seen a few ppl with this but no one ever seems to post up what the cause was sorry cant be of more help dude
Title: Re: Help plz
Post by: topher on 01 May 2012, 23:08
did you change the fuel filter when you did the pump? these cars really dont like being run empty/low on fuel.
Title: Re: Help plz
Post by: inggti on 02 May 2012, 07:16
No. I wouldn't think that would have caused the hesitation and loss of boost would it?. The car does seem like not enough petrol getting threw but then again seems to run rich
Title: Re: AGU engine Help plz
Post by: inggti on 04 May 2012, 15:16
Ok it been 2 weeks and I still got problem. Anybody any ideas wot I can check for. I've got it ticking over and can feel a slight miss fire. And just I had bonnet up wen the revs dropped I could hear it sucking air threw filter. Loads. Anybody??

Post by: navmk4gti on 04 May 2012, 20:40
put standard airbox back on and take that induction crap kit off ..did you change ignition amp then? when my maf went on my agu it drove very rich and was hesitating everywhere.. and what caused it was a ebay induction kit  :rolleyes: but i did not have misfire and all that  :undecided:
did problem get worse after you put in used coil packs?
Title: Re: AGU engine Help plz
Post by: inggti on 05 May 2012, 11:48
It's proper k&n and was on car wen I bought it 8 months ago. So wouldn't think it's that. And it was still same wen I changed coil packs and yes changed ignition amp. My mate has said he worked on a car that was doing same and it was the oil pump. Web that was changed it was ok.
Title: Re: AGU engine Help plz
Post by: Chris. on 05 May 2012, 12:31
Under heavy load/boost ive had AGU coilpacks start to misfire.  Had me and nick puzzled for ages! What plugs you running?
