i have a saph 4x4 i fitted new plugs and put the recomended gap in the plug, test drive for 6 mile very good for a matter of fact it was much better than the old ngk plugs.

6 mile up the road after doing around 80mph it was perfect, now i take a steady drive back home at 55mph and thought shit it isnt going to get me home loss of power taking along time to get up to 70mph but when i got to that it run fine again...

spark plugs are ford genuine part with correct gap i double checked on it.

has my car been remapped or chipped i dont know if it has but would the gap be diffrent from
factory gap...

also battery keeps going flat when the car is left for 2 day's, i found out that the abs unit will pump or make a noise every 15-20 mins why would this be...

 

Sounds like it is over-fuelling to me, fouling the plugs up when cruising. What injectors are you running? where abouts in the rev range is it missing? Was on light/partial/full throttle?

 

yes your right i should of said that it does stink of fuel

i dont know anything about what has been done to it or what injectors are on it

at 2500 rpm in 3rd gear around 50mph its really bad and holds back

 

i also forgot to say with ngk plugs it is bad on idle it ticks over around 7oo rpm

with ford plugs it idles better at around 900 rpm

 

It needs looking at anyway by someone with a rolling road preferably for a fuelling check, but I would check in the ecu first to see if std or not chip is there.
The fave on these is the CTS sensor goes duff usually stinking rich, so I would change that anyway about Ł10 or so, get the co right and then you can adjust if needed the idle speed afterwards.

how do i know if its a standard chip

ive been trying to call stu at ma but never get an answer...

rayland now is my answer

 

how do you end up owning a cossie you know nothing about?

what colour are the injectors?

 

Who's chip is in the ecu,standard or ?

 

my car did similar to this and it was the map sensor.

 

"Ma?"

If thats me I'm eager to know if i have a phone problem.
What option are you choosing as Ive been here all day and only missed a few calls when all three of us have been on the phone at once.

 

BTTT

 

Sounds very much like a m.a.p. issue check the sensor .

where will i find that i know jack shit about the cos yet ive been in to my s2 in the past

 

have a look through the pdf files mate via stus info

http://www.motorsport-developments.co.uk/stus.html

try the health check one

but theres loads of info there if your not sure what your looking for

 

First job is look at the injector and see what colour they are e.g Green, blue, yellow.....

On the passenger side of the dashboard their may be a cover, remove this and the ECU is there.

The plug gap will vary as to what injectors your running.

 

behind the glove box maybe your first job..pull it down and out ahh there it is
