Monte carlo 1.2tsi judder when on power

[MC24]

Hi all, 

 

I was driving home from work this evening, then a judder happens when under power then drives normal it doesn't happen all the time but getting more frequent. 

 

Is it a misfire or something potentially worse than a misfire?  No lights appeared on the dashboard.

 

TIA

This happened on mine, it used to happen from time to time like you say, especially on uphills and under power, then more frequently, it was the plugs and a spark lead.

Agreed, check plugs first, then leads, if your car is pre,2011 and has the unprotected leads (without the ribbed plastic trunking) then no.3 lead commonly fails.

Hi guys, 

 

Sorry for late reply was away with work. Mine is a 12 plate @Filipelol totally the same symptoms all uphill power is bad. @xman mine doesn't have any ribbed plastic around it where is the break in the lead usually at?

Internally. Check the resistance with the multimeter, it should be around 8 to 9 kohms iirc
