My Corsa 1.3i 1998 model lacks power on acceleration to the extent that I have to pump the gas constantly while driving to get any power, it also cuts out after long drives (but not often). - any id
I can get to a high speed of about 100 - 120km/h and nothing more.
I constantly have to pump the accelerator whilst driving because it doesn't have power.
my idling is erratic, after starting, it kinda goes up and down by itself without any
assistance from me.
I have replaced the spark plugs, the air flow meter and the throttle valve - as these were
all suspected or suggested causes.
