Dear fellow Corsa Sport members,
To begin with: my car; 2002 Holden Barina (As known as a Vauxhall/Opel Corsa C, 1.4l Ecotec Engine), we import and re badge them as Holden Barina's here in Australia. 84,000km on the clock, recently had timing belt changed as per maintenance and brake rotors/pads upgraded, serviced with oil and filter every 5,000km. New air filter and fuel filter installed recently. The car has been well looked after. Here it is below...
Things that I need to remedy;
I am unsure of whether my vehicle has a MAF, (Mass airflow sensor), or a MAP, (Manifold absolute pressure sensor). I believe it is a MAP as this is the only part of the sort listed in our parts catalog's down under.
Based on this there are two things the car has been/is doing.
Firstly, as I have approached roundabouts, especially coming down hill with little to no throttle, and depress the clutch, (taking the load off the engine), the revs drop and the car shakes and then stalls abruptly. I have read on these forums before that this can be due to a faulty MAF. Is this correct and if so can it also be attributed to a faulty MAP if thats what my car has as they essentially serve very similar functions?
This doesn't happen very often (6 times in the last 6 months) so I haven't sought to remedy the situation. However after dropping the Misses off at work this morning, on my way home the car began to hesitate around the 2000rpm mark like there was no fuel getting to the engine. The power disappeared and the car felt very flat indeed. My first thought was dirty fuel, (being from country Australia we have issues with this), so I went very slowly to the local Shell garage, (known as the best here for good quality fuel), and filled up with 'Optimax' which is just a standard 98 Octane fuel. The hesitation still occurs. It sometimes lets me rev to 3500rpm if I slowly depress the accelerator however anything above this is just not going to happen. At the moment it is drivable but like I said it wont rev at all past 3500-3750rpm and has, I'd guess, around 55% of its normal power below that.
Some have suggested that similar symptoms could indicate an EGR Valve issue? Is this also possible?
I've tried my best to search online for information on how to read the fault codes at home here but so far as I can tell this is not possible only the Corsa's made prior to 2001, i.e. only Corsa Bs, are capable of the 'paper-clip' method.
I'd truly appreciate any advice. Over here our Holden Technicians, (especially in the regional areas), have no idea about the Corsa's as they are European Cars and our technicians generally are not trained sufficiently to maintain them as well as European/UK mechanics. Also it sounds as if the Technical support and dealerships over there are very similar in helpfulness to ours here... my dog sheds more light on most subjects. 
So what do we think? Am I totally off the topic or does this sound about right? Any help would be truly appreciated.
Cheers,
Anthony, Australia.

I have to go to a job interview some 650km away in two days; don't want to seem pushy or anything but if anyone has any ideas they'd be appreciated more than you know!

Ok, a quick update...
I took the car to Holden today so that they could hook it up to their TECH-II diagnostic system.
They had it all day and gave it back to me at 5:30pm and said 'no faults found at all', 'running fine at present'. They said it must have been a little bit of bad fuel... (hmm... Shell Optimax out of a 2 month old bowser... don't think so!) I also spoke to my cousin the head mechanic at Mercedes Benz in Brisbane, Queensland, Australia. He's the best mechanic I know by far and he says no way to the fuel excuse.
This is where it gets a bit ZOMG...!
So I drive out of the dealership $80- later and guess what? The car wont rev above 3800rpm, it's like its been limited there by something which was exactly what was happening before! To add to that it is now very difficult to start? WTF?!?!
The inspection light has also illuminated so hopefully they might be able to diagnose the problem now?!
The plan tomorrow is at 8am take it to a mates garage to inspect a few things. Then he is going to see if his $14K diagnostic equipment can hook up to the Barina. If not were going to take it to Holden and get the foreman to plug it into the Tech-II again and see what the ECU has logged now that the dash inspection light is illuminated.
These people at Holden are useless!
Help!

Paperclip test won't work on a C.

Ok, took it to my mates garage and plugged it into his 'brand-spanking-new $14K AUD computer'! (Looks like a fancy calculator Lol...)
The car is telling us that the Crank Angle Sensor has packed it in?
Do the Corsa C's have a 'get-home-safe' or 'limp' mode by any chance? There is nothing in the manual about it but they have left other things out also...?
We are hunting around for a price at the moment. Has anyone else experienced this problem? I spoke to a technician here and supposedly the Crank Angle Sensor and Cam Timing Sensor in the C's are known to fault.
Missed that job interview unfortunately... 
Meh... what we do for our cars hey...?
Superlite Ltd.: That part number; is that for the MAP? I've found out that ours don't have a MAF? Engine code is slightly different; Z14XE?

Ok,
Simply for the information of anyone who experiences similar symptoms it appears that replacing the Crank Angle Sensor has done the trick.
The fellow I ordered the part off is a mad keen Holden/Vauxhall mechanic and said he'd seen a Corsa C doing the same thing as mine as it approached roundabouts. (See first post)
He explained that these sorts of symptoms begin to occur as the sensor starts to have intermittent faults. These intermittent faults do not register a fault code on the ECU until they become permanent faults.
So there we go; Crank Angle Sensor. I hope this helps someone else in the same situation now or in the future.
Price for new sensor was $181.81c AUD so guessing about 70 pound? Took me all of 5 minutes to install it. If you have a C, look down between the oil filter and the sump from above the radiator, it plugs in sort of in the side of the sump.
I'll post any further issues if they arise but everything seems fixed. If anyone has similar problems feel free to U2U me about them.

This is a common problem on X/Z10XE's and X/Z12XE's
These sensors are one piece with their own cable with a female plug. The two most common problems are breaks in the wire causing a higher resistance giving an inaccurate reading, and internal pulse reader failure.
There is also a more drastic problem with the crankshaft itself on some engines where the actual magnetic lobe on the crank wears down and provides a weak signal to the sensor.... thats an expensive job and usually results in people fitting a new engine
