had a bit little bit of a miss on the turbo for ages now, but loads of people experience the same "kangarooing" occasionally so just learnt to live with it

yesterday was comin into my road and it died when i tried to pull away from the junction, picked up straight away and drove, thought nothing of it.

today just been to uni in it, seemed reasonably fine all the way there

on they way home it started missing, (when i say missing i dont mean dropping onto 2 or 3 it feels like its actually cutting out)

this gradually got worse and worse, as i got home, had to call into my dads works on the way it got that bad, missing whilst of part throttle, no boost or when pulling away from junctions, only way to avoid it seemed to be reving 3500-5500 rpm and it seemed fine.

got that bad near my house that it was coughing and spluttering and popping flames out the back

totally lost as whats wrong with it. any ideas? gonna leave it to cool down and check some bits or wiring etc, but its full to the brim with fuel and i need it for uni as the clutch on the runaround has given up the ghost

any help please

please post technical questioins in the technical forum

 

paul u girl, its urgent, probably wont get seen there, i need it to be seen

 

and before i forget - check your map sensor pipe and coolant temp sensor for the ecu

 

gonna take all leads off, all connections, check em, clean em, spray em, check teh plugs etc, but it didnt seem like plugs, in my experiences plugs will drop down on cylinders, feels like the whole engines shutting down

 

hence check map sensor pipe and coolant temp sensor for the ecu

 

will do boss

hope its nothign serious, thought fuel at first but seemed a bit suss that its popping flames,

 

sounds very much like what i'm suggesting, or the map sensor could be jiggabood

 

also, doesnt miss at all at idle or when reved, just when underload

 

make sure the chip inst loose either

 

found it

CPS wire, got a 2i fan on the back of the rad, looks like when the engines moving forward, the wire is trapping on the fan between the fan and the startermotor and shorting out, just need to dig it out when its cooled and try and repair it

is this a likely cause????

 

Had a problem like this with my frst, the problem was though it was so intermitant that it never seemed to breakdown when it was on the rollers!! In the end (thanks to well lane!!) they identified that it was a wiring fault on the MAP sensor circiut. If what the other lads said above doesn't work, get a circuit tester and use the wiring diagram from ford or the haynes and tester all the links on that circuit. Mine ended up being some poxy inline resister/contact which is situated at the top right of the engine bay around the ecu. (It is a small black block with a 3 pin connector on it)- if you find it give it a wiggle when it's running if the problem seems to stop you need a new one. The part is not make by ford anymore, you'll have to scour the scrap yards!

Good luck hope this may help??

cheers for that mate, gonna repair this wire and try it,

theoretcially when the engine moves (i,e when setting off etc) its trapping it between the fan shroud and hte startermotor, causing it to short out

just rang msd and had a quick chat with kenny, he said its a possibility

needs repairing either way............

concequently this wouldnt have happened if deflex wouldve sent me my fucking enginemounts, cos mine are worn as and theres loads of movement

wankers

 

just got it off, what a pain cos of the fan

hope i can seal it up and repair it.... its part of the loom apparently

will have a bash later, then tie it up so its miles away from everything



can just see if u look through the shroud on the fan, the wires sticking out, was trapping between the fan and starter


the wire

 

its fixed now anyway

sorted the wire out and wrapped it up, tied it out of the way.....

looksl ike its finished off the plugs anyway,w as in need of some, drops down a little bit when u first come on boost, was in need of a set anyway

now ya mention the CPS wire chris, i had the same on the rs2000 turbo engined XR4x4



would start splutter and choke itself, wouldnt rev or drive very well - wires pulled out the plug and bared and shorted intermittantly - boosh

 

temporary measure cos of the 1 off intercooler set up

need some custom hoses or pipe work making up but its gonna be expensive
