Bought a St170 today 37k full ford history
Gave it a bootfull tonight and on comes the engine light!!!!
Hope this is,nt the start of things to come
Temps ok (Oil,water)
Levels ok
No power loss???

 

get it scanned mate will show you the problem.

happened to me fairly recently after I bought my Ford Focus. Turns out it was just the lambda sensor a bit stuffed. changed that and all sweet.

 

could be a simple as a HEGO giving up...

 

seen a few st170's with hego probs, universal sensers don't last long so spend the Ł70 and get a geuine one!

 

I presume these don,t go into limp home mode then as i,ve still got throttle and the light is on continuosly

 

Get it whacked on the Diagnostics mate. If you was a bit closer i'd have a look for ya.

 

HEGO are only in use on closed loop - so idle and cruise...

 

had that on mine, also had the intake manifold clip break off giving a light I think.

 

Not had bonnet up yet to check
Fookin ford lol

 

talking of stupid ford probs, heres one for you...

when i corner really hard, i mean driving far too stupidly like you should in a boggo 1.8 mondeo, my shitbox mondeos handbrake light comes on, and no, im not using it at the time

No noticable probs at the time tho, wassat about?

 

lad that works for me has had a new lambda sensor fitted in the down pipe 6 times in the last 3 months under warrenty!!i shit you not!!his is an 04 st170.

 

I only had one in 2 years so not quite a bad as above !

 

My ST24 was doing this ...........................top up the brake fluid res !! ......... checked my brakes and i do have a tiny seep from rear caliper

 

I think thats a brake fluid level warning light as well

 

My engine cover isnt on underneath the car as it broke as my car is too damn low and I have an ST170 manifold and flexi on it anyway.

Have a look where the post cat lambda sensor is. It couldnt be in a more ridiculous place even if they tried. Its the first thing that gets hit if the car bottoms out. Brilliant piece of genious whoever thought to put it there

 

Car,s booked in for tommorow for a diognostic test
I,m beggining to wonder if it,s maybe electrical related in some way
When i picked the car up yesterday i brimmed it with fuel
now i,ve done just over 50mile and the gauge is still reading max
After hearing that ST,s are a bit thirsty i,d of expected the gauge to creep down a little bit at least?

 

No thats fine mate and also depends on your driving style. You will find when you restart the car after leaving it for a while it will have dropped down

 

02 sensor!!
Hope this is,nt the start of things to come with it

 

37K service history miles and sensors are going? is that usual?

 

I thought that aswell
Checked the history out today and it,s all genuine the previous owner was in his 50,s
He said the car saw more polish than petrol!!

 

dont worry about the O2 sensor mate. Its minor. Just change it and all will be well. Could have been anything as it doesnt take much to duff them up. Coudl have been running lean for a little bit or too rich or something couldve hit it whilst you were driving. Honestly look at where it is and you will understand how stupid a place its in because of the way its facing.

 

mine has 40,000 and has both sensors changed

common aparantly.

don't sweat it.

how much was it if you don't mind me asking, i'm selling mine and need a guide price

 

Moose i,m ebay,ing this one as well!!
I had it cleared and touch wood the faults not returned
I,m going to give it a couple of week if it don,t come back on i,m ebay,ing the 02 sensor i,ve bought
It was about Ł70 genuine ford one

 

thats what happens mate. that happened to mine. will come back on in about 2 weeks or so. whats happening is the O2 sensor is working, but at some point it will mess up and the ecu will automatically revert back to it original pre-installed fuelling and will not used closed loop so willl throw the fault up that the lambda (O2) sensor has a low voltage/ unresponsive/slow output or something along those lines.


no biggie at all mate.
