hoping someone can shed some light on this problem. i have a 2003 jetta 1.8T and its spudering at idle or driving, plugs are new air filters good, fuel and fuel injecters good,only thing ican think of might be the coil packs it has 96,000 miles on it.

 

Is the CEL light on? If so, have you tried scanning it for codes and see what comes up?

I suppose coil packs are likely considering this was an issue earlier.
