My mk4 golf engine missing any ideas why?

So as it says my engine is missing its jumping the odd time when driving it, and doesn’t seem to have full power. So far iv change the fuel filter which helped it a good bit but its still a good enough miss in it.

I was thinking it might be the coil pack I think? Anyone else have any ideas to what it could be? Its a 1.4 16v engine. Is there a sensor that could be gone because since I have the car a few months now when the engine is cold for the first min or so of driving it would have feck all power and nearly dye if I put the pedal to the ground. Could it be a sensor gone? Or the coil pack, or any other idea guys???

Cheers,

The throttle body most likely needs to be cleaned out. There's has been a few threads covered before about the issue. I'd a similar problem with my old golf. May be worth doing a search for 'throttle body'

As far as I know the coil pack issue is only for 1.8T engines.

I'd check the air filter to see what condition it's in, maybe have a look at the spark plugs to see if one of them is banjaxed. After that look at that oxygen sensor.

Hi Op,

I had the EXACT same issue with my Mk 4 Golf 1.4 last October. Basically the diagnostic showed that there was a cylinder mis-firing. I got a new cylinder lead to replace the banged up one and a new coil pack. The lead cost about 25, coil pack about 145. (If I remember correctly, and both bought from a main dealers parts garage).
I got an independant mechanic to look after it though and he charged me just 30.

I'd be amazed if this wasn't the same case for you as your lack of power (almost to the point of cutting out going uphill) sounds like a match to me.

Assuming this is your issue, you could maybe just buy the lead first and see if that clears it! At the time I had a lot of mileage in one week ahead of me so didn't take the risk.
