I am a newbie to motoring, but I have a problem that I apparently need to research with my own hands (garages either want to pump money by replacing everything in sequence, or tell me not to bother).
I have a 1.0L 1998 Opel Corsa; right hand drive as common here in Ireland. The car runs fine; has a few known problems which I'll list later - first, the one I'm struggling with.
The Check Engine sometimes lights up for a time. And I know how to reliably " make" it light up:
- get up into high gear. 5th will do the trick all the time, 4th sometimes
- speed up so that the speed is not low for the gear. About 60 kmh for 4th, about 90 kmh for 5th
- release the accelerator pedal and let the car slow down gradually without changinggear (or sometimes, *slightly* press the brake)
This brings the Check Engine light on. Then if I press the accelerator (with otrr without changing the gear down), the light goes off again.
I took the car to a garage, where they took a computer reading which said " Air Flow Meter". (I think it was " low voltage" ). They told me to replace the air flow meter; their price was through the roof but I found a cheaper one (insert only) in a shop and got it fitted. No change!
I need to get rid of this as I want to use the car for a driving test, and one can be failed on the test if " a system warning light comes on at any time".
Here are the known problems, in case any of them may point to the cause:
- the accelerator is somewhat stiff compared to newer cars (but still manageable)
- a compression check (in a garage) showed low compression (100 psi) in one of the cylinders; but the car still has enough power to run for now
- the battery is weak; if the car is left alone for several days, it needs a jumpstart to get moving again
What should I check for, try, etc? I have a more experienced friend who can help me with the tricky manual work, but I need directions.
WIll be most thankful for any advice on fixing this.
