9n3 Polo Gti flat spot

Post by suhail.m3 »

Hi,

I've been searching and reading other discussions, but the issues dont seem to be the same as mine.

I have a 2007 polo Gti 1.8t. The car suddenly has a flat spot from about 3500/4000rpm, it loses power and misfires a bit.

It sounds, idles and boosts as normal. The only thing that changed, is that I swapped out the battery.

It happens in all gears, cold or warm.

I am a newbie, so if I did something wrong... I'm sorry.

Get it scanned and clear the errors. Battery swop might have recorded some faults. Could also be something simple as a dying spark plug or coil pack.

Thanks.
It was serviced about a month ago, I doubt it's a plug. It might be the coil pack, someone said it could be the fuel pump but I think it's best to get the car logged.

Don't simply discard a dead plug as a culprit because it was serviced recently. I have gotten many dead new plugs in my life so far.

Sounds like a faulty coil pack or spark plug.
