More Issues....
Discussion
Took the car for MOT last week and it failed on emissions it would appear post CAT. Therefore I needed to go and buy a couple of new 200 CEL cats which I did from Walkinshaws and picked them up today.
Had them fitted as by the looks of it the previous ones were practically non-existent or disintegrated. I could tell something was up a little while ago based on the nasty smell. Anyway to cut a long story short, my local garage cut out the old cats and fitted the new ones. Then they run the car up and for some reason the left cat is glowing red hot. They then called me to tell me that they were a little confused by this. My hunch is that somewhere the system is perhaps running lean and chucking more fuel down the pipe to compensate and the unburnt fuel is in the pipe causing the CAT to glow. Not great at all.
There was me thinking that the CAT's got fitted, the Monaro passes the MOT and happy days....it seems to have other ideas. The MOT centre will be testing it tomorrow to see if it passes but now I am concerned that there needs to be another load of investigations to find what's causing it.
Anyone else experienced anything similar? It's booked in at Walkinshaws again at the end of the month. Getting bit fed up.....

Well it would be very easy for them to see if it is lean.....with a gas analyser, or viewing live data from the lambda sensors on each side.
And under what circumstances was it glowing ?
Just idle, or other ?
And how was the car running ?
For a cat to actually glow red, there would have to be some poor running symptoms too.

It has been suggested that it might be an injector stuck open which is shoving fuel down the left bank and igniting in the pipe causing the high emissions and would be igniting fuel in the CAT. The mot station said that my previous cats were basically completely destroyed and there was nothing left of them, which may have been a direct cause of a stuck open injector possibly. Car failed emissions again utterly, so now I am faced with potentially having to get the car recovered to Walkinshaws as I can't legally drive it until the problem is diagnosed....so another nice round of bills coming my way

can't you book it for n MoT at Walkinshaw and drive it there (pre-arranged test and all that)?Not happy
I find it impossible to believe anyone would be driving a car with an injector stuck open...and there be no utterly blatantly obvious problems with the engines running to the driver.
Well anyone with half a wit.
None of this makes sense, but when there is a lack of actual diagnosis and information available....it wont make sense.

When I bought the car, I sensed a slight misfire. It went into Walkinshaws back in October and that was one of the issues I asked them to investigate. They couldn't find a thing wrong with it. No codes were being thrown up and they could not diagnose a misfire at all. I'd like to think I have more than half a wit, having had a good few cars over the years and worked on them. If you saw my previous CAT's and the fact that they had literally disintegrated, then clearly the car was still running but not throwing up any known faults. The moment I got the car, I changed all of the plugs and leads for the best quality ones I could. I never skimp on anything when it comes to cars, I get the best I can afford as I don't like buying cheap stuff. So if you can suggest what the issue is as the experts on our cars couldn't find it, then i'm all ears fella!Well anyone with half a wit.

Is it worth based on a possible injector issue taking them all off and sending them for a clean rebuild , they don’t cost a lot to be cleaned and if there is a fault you would know , is fuel pump ok and when it was code read is all ok , could a 02 sensor be playing up and running things lean , is it supercharged are you getting any det or other issues , slightly different but my forester sti the hole lot glows red when pushed a bit
from reading up a bit a common reason is a misfire and fuel not burning yes as stated above , so i would re do plugs and leads first and see if that helps as a lead or plug could be faulty which is not un heard of , check coil packs , if that does not work i would look at the injector issue
Thanks for the feedback. I am having the car recovered soon and taken to Walkinshaws. The plan will be to do a full diagnostic check and more than likely sending the injectors off to be cleaned and checked for flow pattern. I noticed the car was running quiet rough when I brought it back today and engine light came on, so hopefully there are some fault codes thrown up now.
We shall see soon I hope as I'd actually like to drive it one of these days

Keep your chin up mate, you'll get it sorted. These cars aren't complicated enough to be unreliable, you've just had a bit of bad luck and your car probably just has one unusual fault that needs correctly identifying. After that it will be spot on.
Keep us posted.
Cheers fella. I am determined to get it sorted as I love the car and am certainly not frightened of spending the money on it to get it right. I will let you know how I get on Keep us posted.

Well I have asked you at least twice for proper emissions data. And I guess this is a 3rd time ?How will anyone diagnose such a problem without this basic information ?
