Corsa b 1996 1.4 8v help

Hey guys first time poster here !!

I'm a new driver and have brought myself the car mentioned in the title as a cheap run around .Over the last week or so I've been noticing strange occurrences with it, for example, Whilst driving to the local shopping centre I was on my way up a hill and changed into 2nd gear and the car seemed to have hardly any power so I tried 3rd at that was the same.so I pulled over had a check around the car found nothing obvious and got back in and it then seemed fine. Since then its been happening more regularly ,up to the point when pulling off at the lights the other morning it stalled(not sure if it was me or not) and would start until I left it alone for a min or two. On that same day whilst coming home from work I was turning a corner in second gear put my foot down for gas and no power, it even cut out on me (I had literally just pulled off).

It also revs at about 1k in idle and does bounce around a little and there can sometimes be a strong smell of petrol coming from the exhaust .

I've since done the paperclip test and its giving me code : 0115. Which is pointing to the Intake Coolant Temperature Sensor.

Does this sound correct, would this sensor cause these issues ??

And for the life of me I cant find this in the engine .no matter how many websites I look at none of them seem to show a clear enough picture where it is.I've got an idea but would like some clarification.

one thing I forgot to mention, the other day whilst checking the oil level I noticed it was a little low so I topped it up with some Castrol gtx magnatec 10w-40.Thing is I've had this oil knocking around for quite a while around 4 years I reckon. Does it go off??

If anyone can shed any light on this id be most grateful

MANY THANKS !!

Cts can cause that icv can also cause all them symptioms

As for oil im not sure if it goes off id imagine it wouldnt be as good after 4 years

The cts is at the back of the engine iirc think its easier seen looking from the bottom

sorry newbie qyestion here

Whats icv ?

[johnny]

Idle control valve you will pick up the abreviations quick enough

Just to update I have now changed the CTS and the car is running like a dream.

Purring on approx 8k revs in idle and power is available when needed.

Bizarre how such a small component can totally disrupt your car like that.

Many thanks btw
