welcome what model do you have petrol, diesel, turbo, na, etc ??
it sounds like dirty fuel injectors or air fuel mix if it is petrol
but need to know if the car is a turbo or not.

RE: Hesitating - Delboy21 - 11:th-Jun-2016

Its1.6 Sri petrol

RE: Hesitating - tucpal - 12:th-Jun-2016

as i said then above
have you ever had any error message pop up
and how bad is this hesitating are there any other symptoms.

RE: Hesitating - Delboy21 - 12:th-Jun-2016

No fault codes or lights car runs fine other than that

RE: Hesitating - tucpal - 12:th-Jun-2016

Your best just to get it looked at or you will be forever changing parts that don't need changing
it would have been helpful to have see the old spark plugs for their condition
you could try an injector cleaner but if you have no error messages and the car feels ok other wise
it may just be fine so get it looked at it is your best bet.

Quick reply I am a mechanic so garage can't repair it if they have no fault codes I have a code reader only thing garage could do was use parts from there stores one at a time just the same as I'm doing just looking for someone who maybe has experienced the same thing

I've been going though a similar experience. Misfires, hesitation, rough idle and poor fuel economy, no engine lights or codes, and even weirder, poor gear changes from 1st to 3rd. Even Vauxhall were confused.
I swapped out the spark plugs and changed the coil pack, to avail.
Then I thought I'd clean the MAF sensor, and it seems to have sorted the problem. Its not 100%, but it will do for the moment until I can get a new sensor.
