Hi,

Just wondering if anyone has any idea what is up with my ST. Lately, every morning (or everytime the car is left for hours). I start the car up, the idle will go up and down, (really struggling) sometimes dies. When I press the gas, it struggles to give me power

The car makes a funny noise, the rev counter barely moves and then it will normally backfire.

After this, if I keep revs up it will allow me to move the car but will loose power again. It will be like this until the engine starts to warm up and then runs 100% fine

I have change spark plugs, leads. Anyone have an idea what it could be?

No engine light or anything is on, Like I say its only when the car has been standing that it goes like this

thanks

Coil pack? Sometimes caus certain misfire/backfire situations... Seeing as you are also at a loss of power too.... I know it's not healthy for the engine but after it's been running a minute try booting it and taking it through the rev range just once... What does it do?

Clean the throttle body ALSO

Hi,

I did rev it as soon as I could get it moving, Performance was fine. After I let it settle and tick over was fine.

Its like if you give it some, it makes it work normal

Im going to be cleaning the throttle as soon as I get time

thanks your help so far

it's a 10 minute job if that bud
does wonders and if it's what I think you're talking about, mine did the same before I cleaned it

Yeah I gave it a rub over with kitchen roll once and that even did the job LOL!

yeah same haha and a very small amount of white spirit

Just cleaned it, can't believe how easy and quick it was. I don't think it was that bad let's hope it does the job. Only thing I have notice so far is the rev is higher when kicking in.

I am going to let the engine cool down for a few hours and try it. Fingers crossed it will b fixed as I've just found out I need four new tyres . Hopefully will b able to get some new alloys as I'm fed up of ppl nicking my centre caps. The st is a four stud right ?

4x108 mate

Not worked

Still not worked, still having same problem. Anyone else have any ideas?

Wondering if it could be the fuel filter?

Very unlikely mate fuel filters take years to clog up.

you'd have to put oil in the petrol tank for that to go wrong.

it's likely that the temperature sensors have gone on your engine, or your ECU has packed in.

i had the exact same problem with my peugeot 106 last year, I had the sensors replaced and the problem corrected it's self a little but was still there.

eventually realised it was the ECU that had packed up.

However the problem was never really confirmed and rectified so i still could be wrong.

But what the garage did know and confirmed some part of the reason the car was not working well when cold was due to the fact i was thrashing it when the engine was cold thus before the car could be heated up to optimum temperature i had put stress on piston rings that were unlikely to be oiled up or had seized under stress and then chaffed.

The engine was miss-firing possibly due to leaks or gaps when cold. Obviously when the car gets hot the metal expands oil becomes thicker so the engine would tick over nicely as if nothing was wrong.

well that was their theory anyways, before that i had 4 garages just say the same thing nothing is wrong with the car.

Well there is but on paper/computer the car's telling you it's fine when it clearly isn't.
