hi everyone i'm new to the website.bin reading a lot of post and you all sound alright ppl

can anyone help me i own a ford p100 fitted with granada cosworth engine and running gear apart from gearbox which is a granada 2.8. everytime i approach a junction or roundabout from high speed it cut's out but i dont know y? does anyone have any idea's y this would be doing is? do you think it could be anythink to do with the gearbox or is there some think else that would make it do it?

thanks

it's because the gearbox sensor is not fitted, there is an easy free cure which my m8 did to my track car xr4x4(24v) can't remember what it is exactly but basicly raise the tick over

post up on here in the 24v section and you will get the answer no prob

edit sorted it

1/start the engine and warm it up..
2/ idle screw (on the left side of throttle body) screw this right in hard and leave it.
3/ once warm disconect the iscv
4/ ajust the butterfly stops till ya have 7 to 800rpm on the revcounter
5/reconect the iscv..

now what should happen, the idle speed will be set manualy above the ecu setting, this means the iscv has less effect but iit will not be needed as much.. it changes the authority of it if you see what i mean..

this is what was done on mine and it's perfect

yep, the youth speaks sense a real common problem.

Jim Galbally

follow youth's procedure


however its to be noted that that isn't a cure to fix a fault, its just setting the base idle correctly. there are similar procedures for pretty much every engine

thanks guy's thats great i'll be doing it tonight. and i let you know how i get on

the reason it cuts out is beacuse of the bobo switch (brake on brake off) which probably isn't connected

if the reset fails to work, go and find tony (maddoldbugger) on fordpower as he'll be able to tell you what the fix is

i tought this is also caused by lack of vechicle speed sensor, which is a trianglur plug on late model mt75 gearboxes or else mid ways on a 2.8xr4x4 speedo cable, which you have to connect to the ecu?

can't remember now mate, but on the back of the box there hsoudl be a secondary blanking plate to fit the speed sensor to as per the granada's with the dohc box fitted and no speedo cable

it's on the passenger side of the tail housing

correct, as on my mt75 gearbox

what I suggested does sort the problem out dojj, mine doesn't cut out anymore and ticksover fine.

indeed guys, nomatter what the ECU is doing if you set the base idle correctly then the engine can't stall. as it doesnt matter what the ISCV does it cant drop the idle below the stalling point

also a lot of the stuff about VSS etc. is actually a load of old coblers. most of those sensors are only relevant to the autobox and won't actually cause issues with the running when fitted with a manual gearbox, the ECU doesnt go into LOS and thats the only thing that would fuck up.

not saying it won't sort the problem, just saying that there is a "proper" way to sort it

but the proper way didn't sort mine.................. i followed m.o.b.s. instructions and all was good...

Jim Galbally

setting the base idle IS propper

also cleaning the throttle goes a long way to curing a lot of idle problems as most are full of crud

done wot the youth told me to and it has'nt cut out again since. think it's solved it thanks for the help ppl
