I have a 2002 new beetle GSX 2.0 gas engine 150k manual trans. Ive had this problem come and go. First thing i did was change all the spark plugs problem went away for a couple days. After a solid week of this coming and going i replaced all the plug wires which have to be pushed down onto the plug very very hard. After this my problem was gone again and has been gone for several months. Now suddenly its back and i have checked all the previous items again. SO, I now wonder about the injector area. Soon i WILL fix this and I relay any new information I find.
damn car!!!!!! Im glad i named it "stink bug" now. -
