1996 1.4 mis-fire

    Changed plugs, HT leads and coil - still the same.

    Noticed a few days ago that it was starting to idle high (between 1500 and 2000 rpm) now and again, then a day later it started mis-firing very badly.

    It's not too bad when cold, but when warm I have no power at all. She still revs fine, but any under sort of load, such as going up a small hill or starting off from a junction, she just kangaroo jumps up the road.

    All ideas greatfully received

    Thats the same model I have got. Never had that problem though. if its an issue with it getting warm why not disconnect water temp sensor and see how it runs, if no change try disconnecting map sensor, and clean ICV, failing that it might be the Lambda failing

    got a brown sludge in the expantion bottle as well. I'm scrapping it - spent more than it's worth on it now. Body is great, just spent 50 quid on new brakes on the back as well...never mind

    He didn't say he's got a problem getting the engine warmed up.
    ICV and lambda will have nothing to do with missfires.

    Sounds like head gaskets has blown, all your problems indicate to headgasket failure.

    The sludge mayo/brown like stuff is the oil mixing with the coolant, your fast idle is one cylinder drawing air from another or another source due to headgasket failure, and the loss of power under load is because 1 or more cylinder(s) is loosing compression due to head gasket failure.

    he did actually "It's not too bad when cold, but when warm I have no power at all"

    Can you not READ or something?

    The IVC has something to do with " idle high (between 1500 and 2000 rpm)"

    and the Lambda has something do do with "kangaroo jumps up the road" if its overfuelling

    But its obviously the headgasket, the OP didnt tell us until I had already answered.

    If he has an issue with getting it warm then he wouldn't have wrote..........."It's not too bad when cold, but when warm I have no power at all" because he wouldn't have been able to get the engine warm in the first place lol. So yes actually i think you'll find that i CAN read and you cant!

    Also it's called an 'Idle control valve'. The ICV controls engine speed when no throtle input is used between 800ish-1200/1300ish rpm iirc. No way goes as far as 2000rpm as the op's problem. 'kangaroo jumps up the road' could mean a million and one things. Specifically picking the lambda is completely random, without working on the car it would be impossible to diagnose the problem from the description the OP gave.

    Wrong again, I obviously know what and ICV is the ICV [which I wrote in my first post] can cause revs to go over 3000. Its well well documented on here, can you not READ or something?

    Wrong again, I didnt pick the lambda at random, I suggested eliminating other cures first, can you not READ or something? Ok then bore us all with these "million and one things" are. Im going out, its a mad house in here.

    "without working on the car it would be impossible to diagnose the problem"

    DICK HEAD! thats what we are all here for - diagnosing the problem without working on the car! The OP wouldnt be asking us otherwise.

    You are thickest member I have come across so far, and there have been some thick ones!

    Your insults really show how imature, pathetic you really are. Your wrong about 99% of what you post, why do you think you have so many misunderstanding with soooo many users? Because your wrong, always.
    If you don't agree with someone, even if they provide evidence to back them up, you just turn to insults. Your pathetic...........I will be doing my best to avoid you on this forum....and other people would be wise to do the same!!!! Hope you have a good evening and may god bless your poor soul!

    i had the same problem with a 306, it turned out to be one of the cylinders that had just completely lost compression, hope its not that though man, expensive to sort out :/

    Jeez, a few arguments going on up there!

    Bit of an up-date - I spoke to my old man about it today as it's my mothers old car - the sludge has been there for years, so could be left-overs from a previous (unknown) head gasket failure.

    going to try a different throttle body from the scrapyard tomorrow. will update then

    Try flushing out the cooling system to get rid of the sludge,but 1st do a sniff test of the coolant if it smells of petrol then thats a sure sign of HG failure.

    defo sounds like headgasket, sounds like one of the cylinders is loosing compression

    k - a bit of an update

    drained and flushed out the coolant, just with a hosepipe, and fitted the new throttle body. took it for a spin and it was 1000 times better - not right but definately driveable.

    took her out again about an hour later and it was back where it was on the weekend - absolutely shite. also, either i didn't bleed the coolant through properly or the head gasket (if that's what it is) is getting worse, because whenever i blipped the throttle i could hear air bubbles through the heater matrix.

    one last thing before it goes to the breakers - could it be fueling? any in-line filters (seen a silver canister off-side rear underneath) and where's the fuel pump on these things?

    that should be near-side not off-side obviously
