EML on . decat

[jam123]

I've been reading around but dont know what to do really, have decat, engine light on seems to be overfueling a bit - EML light is on and off, somtimes badly sluggish at cold start up? badly overfueling? too lean? I have one lambda sensor in and the other sleeved in engine bay, what do you suggest. cheers

Try moving the 2nd lambda sensor to somewhere that gets a better airflow past it,or change the sensor.

The engine management light you have is because of the second sensor that is in the sleeve. All it is telling you is that the cat (which isnt present) isnt operating as it should do and cleaning air properly. It does not alter how the engine runs, does not alter fueling or anything.

Basically, the engine knows no different to before when you had the cat on. Providing you have the sensors in the correct way round anyway.

Oh right, well I have had some problems with it, somtimes it use to not go over 3k rpm but doesn't seem to do that recently now weirdly enough... Now early start in morning and i go to pull out a junction and it feels like it wants to stall, foot will be flat down and no power then suddenly kick in. only does this when cold, and like i said seems to be overfueling and somtimes sluggish powerwise

Why do you want to go flat out straight away on a cold engine haha

when it doesnt rev over a certain RPM like its hit a limiter then its usually the crank position sensor.

made me laugh haha

I dont ever go flatout when cold ... lol... when cars cold after having it on for 2 min, I go to pull out at a junction and car just feels like it wants to stall even with foot down... nothing mechanically, definetly to do with decat/lambda sensor. It'll then be fine after that just EML light -____-
