Goodday I have a corsa 2005 1.4 lite. My vehicle rev's randomly sometimes too high and other times so low is cuts out while driving. This happens at random there is no pattern to it. Problems I have looked at and parts I have replaced already. Idle switch was replaced a year ago. Vehicle was serviced two weeks ago. The ignition coil was replaced 4 months ago. please help.
Check to see if it has a Throttle positioning sensor. A faulty one will cause the engine not to run properly. It will do like you described with the engine revving and then wanting to cut out.
Sounds like you not getting enough fuel. Try replacing you fuel filter which sits under neath the rear near the tank. Just follow the line from the tank and you'll see it or it can be a faulty fuel pump You should get 3 bars pressure from it.

Hello
The
Engine and Automatic Transmission (not applicable to manual
transmissions) in this vehicles drive train are fully
electronically controlled by a computer called the PCM and TCM (Power
Train Control Module, Transmission Control Module). When a problem
like this or other drive-ability related problems occurs the computer
stores a record of the problem (there are of course some exceptions
to this, like the fuel pump, engine coolant temperature sensor and
MAF sensor for instance) in the form of a fault code in its memory,
to read these fault codes you must have the systems memory scanned
with a special tool. Once the fault code(s) are read you then must
perform the appropriate diagnostic testing to find and resolve the
problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED
TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD
EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM. Also always
check fuel pressure for correct spec for your make and engine type.

I heave the same problem on my Corsa B 1.0 2000, engine cuts out, and whe it happens, I hear one of the relay under the right side of the dash buzzing. After a couple of minutes, starts like nothing happend.
So far I manage to find that the speed sensor is faulty, when I tap him the car stops. I order a brand new one, but I'm not sure that was the issue.
I order also a Opel Tech2 tester from ebay and it has to arrive next week, then I can see the error code.
