Re: SERIOUS cutout at 2-3k-URGENT

I found that the original vac hose to map was constantly splitting, along its seam, I swapped it for another piece of similar hose and that did the same after a while.

What I am using now is some black washer pipe hose from a ford escort, it has soem sort of braiding in it and is more plasticy than rubbery, no problems with it at all.

good idea that, the only problem with my silicone vac hose is over time the oil contamination makes it go black and eventually corrodes through! cant see that happenening on an N/A engine tho.

Re: SERIOUS cutout at 2-3k-URGENT

still that problem, its not always, sometimes its fine sometimes not-when around 2-3k, its loosing revs/power-need to press clutch, press gas, rev and its fine again, looks no matter of temp

it was allright before new clutch, cvjoints, radiator, etc.. I hope its only some bad conenction, or could be a resetted ecu issue??? (battery out for few days) because no changes to engine(except leads and plugs-is 0.9mm gap right???)

maybe its still that vac hose(maybe hose isnt too stiff and its changing its diemater)

but why only at low revs, and at high its running great..???

I have parts from 899cinq- is lambda, and map sensor, and other sensors the same. ???? could swap them for a try

thanks

Re: SERIOUS cutout at 2-3k-URGENT

Here's something you could try for free: swap the two lambdas, it's a 30 minute job at most, see if that helps.

Re: SERIOUS cutout at 2-3k-URGENT

Some people reccomend heating it first, some say to use a lambda socket, i managed it without (iirc, it was a 22mm spanner). Best do a search first.

Re: SERIOUS cutout at 2-3k-URGENT

thanks for help, it was finally(as you said) lambda sensor-i didnt notice before that cutouts are not when cold,
swap lambda with 899's from scrap(its same, 899s have longer lead)-running allright, idle is much better

btw. swapped more things from 899 engine, throttle pos. sensor is the same, map sensor too, vac hose is longer but same, idle control valve is different


worse thing is smoking, sometimes a lot sometimes not, its white/grey smoke, couldnt notice coolant loss yet (200miles done), theres few drops from exhaust, smells not like coolant, also fan is starting at 95degreees(which i think is high), temp going almost to 100 degrees while not moving, but will not boil-could be H/G leaving me or waterpump(didnt change it together with timing belt)??? 70k mileage.

Re: SERIOUS cutout at 2-3k-URGENT

Could just be the cat getting cleaned now the engine is running properly. If you are not losing any water, do not panic.

Cheers

Re: SERIOUS cutout at 2-3k-URGENT

Lambdas keep dying???

cinq starts to make me f***ing mad..

swapped lambda, start engine, done 80miles, running allright, keeping at 85-95 degrees, cruising at 1500-2500, no problems at all, city, regional road, accelerating nice, idle nice(yupi).

today checking coolant, at max, running through city, 85-90temp, no problems,10 miles done.
afternoon, start engine, warm up till 85-90 - again serious cutout at 2000 when moving(not accelerating, while keeping the same revs) from lights, then several cutouts through city.

stop engine, disconnect lambda(injection light normally turnedoff after secs and didnt come out when running), engine runs bit rough but no cutouts.
stop engine (still warm), connect lambda, cruising 1500-2500, running fine, stoped car, running idle, engine went to 110 degrees, no boiling, just pressure, moved with car, cruising, temp went down to 85, again serious cutouts....

WHAT THE HELL IS WRONG WITH IT??? next lambda sensor gone????????

no mayo on both caps. coolant, oil looks normal. just white smoke - sometimes. and pressure in expansion tank.

ANYONE have an idea??? why isnt injection light showing disconnected lambda??? should be HG gone??? couldnt be some wrong petrol????

really appreciate your help...

Re: SERIOUS cutout at 2-3k-URGENT

my lambda sensor caused the same faults, thats why i suggested it early on in the thread, shame there so exspensive new, after i fitted a new one in mine it was pretty much perfect, slowly going back to how it used to be now
