Hi all

Hope you may be able to help me. For the past couple of weeks my car has been hesitating at around 1500 rpm when it's first started up and you pull away for the first few times. I don't pull away with loads of revs but I don't remember the happening previously. As I say it's only the irst three or four times you pull away Fromm light or junctions etc.

I've recently fitted a new set of ngk spark plugs an air filter and a pollen filter. The car starts and idles fine. It's a 2009 fiesta zetec s 1.6 petrol.

Many hanks

Were they Ford approved spark plugs? After market ones tend to cause problems. I had this on my mk6 fiesta when it was cold it'd misfire and hesitate when driving until it warmed up. Turned out to be the coil pack that needed replaced. If its not Ford approved spark plugs it could be them thats causing the fault, otherwise it could be your HT leads or like I said a coilpack thats needed

Hi

Thanks for the reply. No they are not ford approved. Just aftermarket ngk ones that I got from eurocarparts website. Ill ave to go to ford and get some genuine ones.

Thanks for your help

Adrian.

Let us know how you get on :)

I had similar issues with my old 1999 Fiesta that I used to have after replacing spark plugs, turns out the timings were ever so slightly out on them. Timings should be in your owners handbook and you can buy timing gaps (can't remember exactly what they are called?) from places like the range.

To be honest, replacing with Ford ones is probably a lot easier and might work out cheaper (although I doubt it with Ford prices).
