s2 help plz h reg

i dont know why but normally when i start my car it idles at 1.5k but when slightly warm it goes bk down which has always been fine


but 2day it went to nearly 2k and when i drove it for 10mins it went from 1k -2k 2k-1k and so on. this happened to a punto i had b4 and it ended up being the IDLE CONTROL VALVE. needed cleaning with carb cleaner.

could this be same problem????

to fucking top things up too my heater has all of a sudden stopped blowing hot air out lol. just cold air.

2 THINGS GO WRONG THIS MORNING.

my car has been sweet up to now????????????????????


eny suggestions

thanks

 

Cold air! sounds like thermastat not opening,Or maybe head gasket starting to let go

 

Heater Matrix? try flushing it out

 

definately the heater matrix... dont discount the headgasket etc but try the heater matrix. Fords systems are self bleeding and so there wont be an airlock and in there designs they put the heater matrix at the bottom of the system to prevent any air bubbles getting trapped. As a side effect of this the heater matrix gets clogged with shit.
I took mine out, took about an hour and it aint that hard, just fiddly. I flushed it through with a hose on on highish pressure.

As for the idling, im not sure, have you checked the connectors on top of your dizzy cap as this can effect the idle sometimes, mine was loose and earthing on the block, it made for the shittest running i have ever had lol!

 

i bet that is fiddly taking the heater matrix out. i was looking at it 2day and couldnt work out how to get it off. i did just litreally look.

i will look at the connectors. but i had rolling road tune 2 weeks bk and they didnt seem to spot anything wrong then?

i will have a look

 

I'd flush the matrix, thermostat only controls water flow to the radiator it's always flowing through the head/block and heater matrix.

But first check the cable for the hot/cold control knob, may have snapped or just come disconnected.

Always check the basics first!!

 

was finkin that. gna take panel off where the knobs are and check wires first. does that come off easy.

flushing the matrix will come next as it aint a quick job lol

 

Yes mate, pull the knobs off (), and then just undo the 2 screws you can see!
Follow the cable to where it goes under the dash (get to it from drivers foorwell IIRC) thats where i've had it come off before.

 

it was running sooo shit 2day too. like i sed about it revin up and down on idle. and if i was to drop down to like 2nd and slow down abit it would judder a bit. 1st time its happend, soooo anoying, car was running sooo sweet

 

just pull the hoses off the matrix on the bulk head behind the engine and flush it out in situ. no need to remove it.

 

heater matrix is easy to remove anyway.. just need the right tools and its done

 

it could be the metering unit that is making it run shit.. i know mine ran bad a few times and it turned out to be the metering unit.

 

well cheers lads. u gna fukin laugh. cant believe no-one thought of it.

it was like the coldest night of the year last nite and i didnt put my car cover on AND I OVIOUSLY AINT GOT ENOUGH ANTI-FREEZE IN THE COOLENT. coz when i finished work and started it the heater worked and blew out hot air agen loll.

so looks like i need to top up with anti-freeze

 

always make sure there is enuf anti-freeze in the coolant

 

lol, nice problem solving mate, lucky you spotted it now else that water can freeze and your block goes pop!
