Escort Cosworth Problem - Emissions
I have a 1992 K reg, escos with the usual stage 3 spec; greens, -31, 3 bar, bayjoo chip, s/s exhaust, rs500 style intercooler etc. I took it for MOT yesterday and the CO reading should be no more than 3.5 % for a non-cat car but mine is reading closer to 11% The MOT guy wasn't much help but said it could be the lamba sensor as did a few people I know. Can anyone else shed any light on this?

Hi Phil,
has the car been re-mapped yet as it was running well rich when i saw you last in it? Could be the lambda, but could be the chip too or a temp sensor/temp sensor wiring problem. Saw one once where the ecu thought the engine was constantly "cold" so was constantly chucking loads of fuel in.
I'm no expert at all, but i'd get that looked at as if it is overfueling massively, it'll not be doing the bores and engine in general very much good.

had problems with my old S2, the cheapest, easiest way around it is to find an MOT tester who is willing to bypass that area of the test.
so you both would be quite happy to be driving a car that's NOT running correctly and more than likely causing damage to your engine(due to bore washing) than pay to get it sorted properly
m8 go and get it looked at b4 it's too late would be my ONLY advise!

I haven't touched it Si because there just isn't anybody local I would trust tbh and haven't got the time to drive 100's of miles for someone to do a crap job like they did with the S2 lol. I don't think it's overfuelling massively but definately needs sorting. A friend of mine did a fault code test where the light flashes so many times and that was pointing to an ecu fault. I have tried a chip from Tony as you know and that made no noticable difference. I just don't want to be throwing loads of money at it for it to be no better than it is, like I seem to do with the S2 Anyway thanks for your advice mate and I'll see you soon no doubt

Thanks Tony but according to the service history the head was reconditioned not to long ago and it looks like they used the green genuine ford gaskets which look in good shape.

Chip, it doesnt fix the problem...
Maybe 11% is too high just to ignore it? I dont really know how the figures relate to the severity of the problem but mine was fine.
Also, the government say 3.5% is legal. We can't assume that anything higher than that is suddenly a "problem" with the car, can we?

Not cause the government say so, but simply cause its about 22 times what it would be if correctly tuned and functioning properly!

Phil, I cant believe you have waited for the MOT to get this sorted!
Its been overfueling like a bitch since you had it, aint it?
Pay the money, spend a day in blackpool and get Stu to sort it out before it fcuks up bigtime!

TBH Chip I'm just being a cunt cause I'm sick of spending money on cars but I guess we are all guilty of that!
Does anybody know prices from MSD/NMS for a chip and setup or just even a setup for my car?

if you don't want to travel to blackpool to get it sorted there are loads of specialists near you that can fix the problem.
nms, coventry
pj motorsport, wolverhampton
reyland, brum somewhere
turbosystems newcastle under lyme
any of them will get your car running properly..
they are specialist for a reason, they work on these cars every day and have probably seen every issue you can possibly think of and found the solutions
of them stu at msd and tony at turbosystems are ones I can personally recommend after using both in the past..

Thats high whats the tickover like?
Tony,why would a leaky inlet gasket make it run rich?if you have more air then it would run lean??it would give a high idle speed
And how do you reset the ecu by unplugging it?
Imo i'd be tempted changing the cts first or borrow a know working one to try

the p8 BT escort cosworth is mapped speed pressure throttle angle
the ecu has a reset feature with ignition on and bridging three wires in a given time period to reset the adaptive memory
with the p8'scomplex limp home and error mask facility it is clever enough
to substitute most values for the likes of ect
technically it can run with out a ect

it is a manifold absolute pressure sensor system not an afm system

As for the running rich with a leaky inlet gasket would that be the same for any cossie L6/L8 or just the P8 due to the complexity?
Reason i ask is a mates car is running a bit rich on tickover
