Hey folks.
My girlfriends 1.2 16v occasionaly hesitates when you put the foot down at low revs, or go to pull away from junctions/standstills.

I've fully serviced the car, replaced all filters & plugs.
I've tried the coil pack from my car as it's off the road, didnt help.

I'm just wondering if anyones had anything similar and how you cured it ?

Just to save me wasting time trying different things.

Cheers

Try swapping over the airflow meter. If its not that then maybe try camshaft sensor or temp sensor.(Post should be in help zone tho mate)

Yeah there no EML which is throwin me off a bit.

I was gonna try and hook it up to the Diagnostic computer @ work (Am a Renault Apprentice Technician)
I know you can access certain other cars thru it but not sure i'll be able to get into the Corsa's computer.

Cheers for the input folks, i had considered swapping AFM's, but i suspected that the EML would be on if it was the problem.

my bet was the coilpack, it was what i was going to change next, i dont know if the panle and drilled box causes the problems, and theres a slight plutter at 4000rpm sometimes

when you change it mate, disconnect the battery for 10-15 mins on the car mate. This will clear the codes from the ECU memory which can cause running differences if they are still stored in the ECU
