Ford Fiesta ST150 MK6 Issue

[Nedny]

Sorry If this is in the wrong place, I'm new to the forum.

I have had a recent issue with my car and was hopefully wondering if someone could help me.

The problem is when my car is started it seems to stutter, causing the revs to drop very slightly each time it stutters. It also happens when driving but not at high revs. 

I thought the problem was due to the cold in winter as its the first time I've owned it in the winter, but I am still having the problem. It's a very slight stutter and didn't really seem much of an issue as later in the day I had no problem, but the engine light has recently come on and I'm thinking its probably a bit more serious then I initially thought.

Has anyone got any suggestions as to what it may be?.

Cheers in advance .

if the engine light has come on, then first you need to get the codes read , either find someone or garage with a reader to do it for you or buy your own. with those codes you can narrow down the issue and then we can help.

without codes your guessing and can end up throwing parts on until it fixes problem costing more than you need to.
