How would my Escort Cosworth act if my Lambda was broken???

My car startes perfect.. cold and warm but it startes with VERY BLACK smoke (for about 30-60 sec) and when I give some throttle I cant see any black smoke.. might the pressure that blows the smoke away.

If you say overfuelling well ok.. I am very sure it uses some more fuel than before I noticed something was wrong and my rear bumper got very sod black around the exhaust, but it dont cut or do limp mode.. and it boost with no problems.

 

I would look at your CTS first or rather change it if doubtful.

hmm..it is brand new, well all my sensors beside the Lambda is brand new sensors, and my very smart IAW monitor shows that that everything is as it should be, BUT the only info I dont get from my IAW it lambda info, cause (so fare I am aware of) the chip (COLLINS) dont send this info out to my IAW.

COULD this be a lambda?? Or would the car act in an other way??

I could drive to a garage and get a CO test .. but thats not possible when I must sit here all the time read PF posts

 

Black soot is running very rich, lamda would not act up like this normally, it would do it all the time.
Iit's NOT going to show up, a faulty CTS as it has such a wide range , it is normally within range just not at the resistance it should be at the temp it should be.
Do you have another lamda to swap in there to try, old one maybe if not just get the metre on it when cold/hot and see what it reads.
Obviously there will be major problems if no lamda reading is getting to the ecu, so after checking at lamda if ok check at ecu, check also if it has a HEGO sensor the heater circuit.

But I can see what you mean.. something is wrong when I get real soot on my bumper.. correct??
I will check things up as you describe.. thanks and you may comment my red comments if you cant sleep

 

Can't comment on the IAW stuff as don't use it.

Check the MAP sensor reading when you start it cold at idle are similar
to when its warm. Maybe do a datalog cold and hot in ILD encoded data and send it to me and i will have a look for you.

 

)can`t beat that for an answer

this is why my rs200 will be going to stu when running (in a few years

I send you a log (email) recently and you said ok for it .. I have done it cold and warm and they are very alike (map sensor).
Have checked everything, especially mapsensor and CTS and they work VERY well, thanks good for that (they are in fact new )... only thing I have been unsure about was the lambda. Had a co-test yesterday, and it "only" said 7%

By the way.. I also tryed to disconnect the lambda etc.. and only the lambda makes NO difference.. so.. well.. it speaks for it self I guess!

I will get my lambda in a few days.. I will keep you posted
