I don't belive it !!' :mad:

 

Looking forward to going to Japfest next week ; took the Zed out for a spin the other day and guess what.............. :shock:

 

I now have the dreaded missfire and Cat warning light. :headvswal :headvswal

 

So having looked through the history of problems with the 'Cat over heat' looks like I have some checking under the bonnet to do :cry: .

 

Life goes on, hey ho..... :tongue:

do an ECU diag first, then also worth checking to see if the AIVs are blocked/filled with water, have you heard a lot of gurgling from either footwell?

I guess it could be unburnt fuel in the cat also or maybe collapsed cats, in which case just chuck em and get testpipes ;)

Ok I know this sounds a bit stupid but mine did exactly the same. I was told to push all the plug leads down and it solved it? It is a common niggle apparently?

You couldn't really see that the offending one was high unless you looked really close?

right oh marcus. i'll come av a look at the zed for you do the ecu check etc. but sounds like it's just a coil pack off, so unburnt fuel is going into the zorst making the cat light go on. i'll pm you me No. if i shrews tomoz for diving so might be able to get up there earlier depending on what time i fin work.

Yep, as Scubie says. Clean the coilpack, CAS and PTU connectors :)

Cheers Scubie mate; I am about most of the day.

The trouble i have is its very hard to get to any engine parts from the wheel chair so my mate normally comes over to help, he has been busy this weekend so if you are in Shrewsbury it would be great to meet you mate :duffer: well do you a coffee/tea anyway :)

 

I will pm you with my home No so you can just check i will be about.
