Engine Management Light 2

I thought I'd open a fresh thread to help anyone else having problems and can read up on what stage me, Drifter and Pinkrinse are on...  A little update from me. I think I may need to get my Engine Light sorted sooner rather than march because I've never noticed it till this cold weather but while running the car and digging it out with a shovel from the snow, me and my fiancé can smell how rich it is coming out of the exhaust and it can choke you after a while!  I hope my CAT isn't knackered!?  It can really choke you  But the car runs really well!?  Any help/info peeps? Question for Mike and Dave T ST? = When I get my injectors and 2nd custom remap do you think that will rectify the problem of over-fuelling richness? Many thanks in advance for any help you guys can give!

Hey Kaxe, dont know if I mentioned this before. My engine light is still on with the P0172 and I too have that very rich smell, BUT, I dont have a cat.
For diagnostics picke it up as P0172-E3, where E3 means unserviceable or incorrect injectors. My overfuelling is happening at idle, so the Ford guy reckons my injctors are shot, and "dripping" at low RPM's.
I played around with High Octane fuel (120Ron) and Octane Boosters, this could have fried my injectors.
Yeah I think mine are dripping at idle

What fuel are you putting in it Andrew?
Mine smells really rich when running on super but smells fine on normal unleaded (as long as it's not texaco)
Not had the warning light on for a while now and the car has only been doing short journys so lots of extra fuel for when it's cold. Hope you get it sorted out soon but maybe your car is hinting that it needs the sc to use all the extra fuel 
I use BP all the time but now and again trying shell and Texaco to try and see if different fuels help. Never touched cheap super market fuel... But nothing's helping...
Yeah I think they've pushed mine to the limit with the custom map and it's just screaming out for SC lol 
It did do really well on the rollers. Jamie said the power bounced up to 205bhp ( drools lol) but brought it down so the engine doesn't work too hard which is good... But it has potential!

Always reckoned the one of the two codes I had that threw the EML light up was because of the sports cat. Nowt wrong with it, its just too free flowing heh

As Steve says, not so much the sensor, but the Cat that needs heatwrapping
I remember talking to Davetst at length about this and the best solution there was is to heat wrap the manifold. Because the cat sits so far down on the st it dosn't really get hot enough to work at it's best. By wrapping/ coating the manifold you would keep the gasses hot for longer and get the cat hotter and working more efficently.

Hi Guys, yep heat wrap or coat the whole lot from the manifold down to about 4" past number two HEGO.
The cat just doesn't get hot enough to perform properly.
If you have no cat on at all then the only solution is to re-map to ignore number two HEGO.

Even standard catted cars will get a benefit by doing this BTW
