nufink but problems
hiya peps. iv had nofink but probs with my 90 rwd cosworth. it broke down soon after buyin it. i changed the ig amp n it ran
.
however its always missfired when warm under high boost.
the other day i was driving it n the missfire became more frequrant n it died on me!
since then iv changed the coil. dizzy cap. and plugs.
checked for sparks at plugs. ok
had both the amps checked n both seemd ok 2.!!!?!!!
the car starts now but it really badly missfires. it wont idel without reving.
n theres shit load of smoke cumin out d exhaust!.
iv cleand the crank sensor.
any ideas any1 plz

Try the diagnostic connector - it's really simple to build and might tell you what's wrong. Then get it to a tuner for setup - best money you'll ever spend.

As it's new to you, I would do a few things to it, a fanrewire and a fuel pump rewire are an absolute must, even on std power.
Check the phase sensor(in dizzy) wires are not all cracked and broken off insulation.
I would also change the fuel filter, then the CTS then get it set up for a fuelling check.

dont fink its the gasket. it broke down while drivin.
iv had 2 peple out 2 look at it now.
1st thinks its a broken wire on the ign system
2nd thinks the turbos gone!!
let me discrbe wot its lik...
when is turn it ova , itl go 2 fire but it wont but when i give it gas itl slowly cum alive.
alot of white smoke cums out the exhaust n u hav 2 rev it or itl die.
futher 2 this while keepin a steady rev, itl stop missfiring for 2 secs.
rev up normaly then return to missfire!!???
iv got no oil cuming out my dump value, n a turbo breakdown wudnt cause a missfire wud it??

iv inspecked n cleand all the connections...
down to the crank...
to the dizzy....
inside the dizzy....
the wires in the dizzy look gd...
iv took the crank sensor off 2 clean but havnt moved the gap...
it seems lik something broke down cuz its been missfiring under peak boost.
n if i remember right it was major overboostin just b4 it broke down

The phase sensor wires don't have to be broken down for the phase sensor to be faulty 
From your description this would be the first sensor i'd change
Also check the loom plug where the CPS plugs in. The pins in there can go dodgy on the engine loom side, making it seem like you've a faulty sensor when you don't really.

I had a similar problem where it wouldnt start , got it going and held the accelerator pedal to the floor and all it did was pop like mad and the revs never went above 3k then died , pushed the pedal slowly and it sounded ok then died . Turned out to be the map sensor wiring .

As said check the CTS I would say thats most likely it's right at back of cylinder head (Left) the smoke you are seeing is probably where to much fuel is being used due to the wrong value being supplied to ECU. Car should still run even if you unplug phase sensor albeit not very well as will over fuel as the injectors will just run in batch.

You can mess around changing this and that or take 30 min max to see what errors show up via diagnostic port. It will tell you if there is a prob with phase sensor, cts or map plus other stuff. Do search for 'diagnose connector' or look on page 4 of this section as it was only about a month ago it was posted. Fitted an led into my dash today for constant monitoring and is litteraly 2 componets: a resistor and led. I will even send you the parts you need free if you want.

I've judged posted on that thread so will be back at top of page 1 again. I can make the circuit up and post to you so you just have to connect one end to battery +ve and other to
output of port.

i had a fault on my car. It used to missfire like hell when the engine got warm and it used to smoke like fook. The water temp sensor was faulty. Have you checked the spark plug gap.

just a couple of points. you said its pouring white smoke out the exhaust?
white smoke = water in combustion chamber/exhaust
ie if what everyone was saying about too much fuel then smoke would be black.
white smoke = water
blue smoke = oil
black smoke = too rich fuel
plus the misfire could be coolant in combustion chamber.
just do a combustion leak test and check the turbo as easy to check. ive been a mechanic for 15 years so im not just guessing.
hope that helps, cheers gary.

iv changed the plugs now. it had racing hard 9s ngk in it. all was black but lookd fairly new. tested spark 2 wernt firing. so clean n heated them on cooker n tryd again. all sparkd fine. tested car the same.
i then bort sum new ngk6s. tested them seemd beta.
tested 4 week spark then. n it seems fine 2.
iv replaced the fuel filter now 2.
starts easy nuf, stil missfirin n still sum white smoke.
you can propa here the missfire thru the exhaust.
also the ice temperature warning lights n the centre consol has stop working 2. is an air temp sensor ?
oil n water as they shud b.
levels fine n clean.
im gona try n check the sensors n wiring from the ecu

Theres a sensor behind the front bumper for ice warning light, Did you gap the new plugs? Also check condition of ignition leads including LT (King) from dizzy to coil.
When you say white smoke your not confusing this with condensation are you which will dissappear once upto temp.

news . started it 2day. n it started 2 wot looked lik fuel n oil out of the exhaust manifold on chamber 1. took the plug out n it was clean compaired to the others. n there was a lot of steam cuming out of the chamber 2.
the water level looks fine still. but the oil level is very high ,over the limit.
i did put alot in it not so long ago becuz it had completly ran out.
the engine started 2 tick abit 2 after a while.
so it does look like my heads gone

Dont sound good dude. Really need to keep an eye on ur levels can easy fuck a motor through oil starvation . wouldnt have thought that alone would have popped the gasket. do u know what gasket its runnin . As u were sayin it's runnin a bar and a half of boost, i assume it's runnin 803's and a stage three map ? to me does sound like its a sensor or ecu related .

My bet would also be the gasket, as you said it went near 2bar at overboost, could be the reason to blow. Also the smoke is a good sign for the gasket.
Do a compression test to find out.

iv only just bort it. dnt know wot gasket it has or wot stage its at.
i have bin checkin the oil. n in two three weeks it eat all the oil. but it had no leaks.
i did think it was a sensor just missfirin. overfuel or sumat, but now its got2hav blown the gasket inside enit

If it's eatin oil at that sorta rate dude u deffo got a prob,u need to find out what ur motors got under the bonnet coz if it's on stardard ecu and injectors and runnin 2 bar then it's gonna melt ,would tend to agree now that it's gonna be HG although could be worse that that so u need to compression check it and sort out a fresh top and , Make sure u go for a group A gaket or better coz a standard prob will fail in no time at the sort of pressures ur runnin, then i'd be gettin a ful set of sensors or at least ECT, Phase ,cap ,arm and get it to a tuner to make sure of the set up . hope u get it sorted buddy looks like a nice motor

Have you not done a compression test? It will take all of 5 mins and tell you the state of the headgasket before you go and take the head off.

overfueling due to the misfire, will cause bore wash & the oil to thin so it will burn it which is probably why its used loads while driving it. change the cps & coolant sensor first after that map sensor & phase.

hes running a standard engine, turbo etc. he has a stage 1 chipped ecu, -31 actuator and a full exhaust, k and n panel filter thats it. everything else is standard. the car was running and holding boost at about 17/18psi.
