    evening all was on my way home from work and hit some traffic and my car was thudding evhttp://www.audi-sport.net/vb/newthread.php?do=newthread&f=17ery so often almost misfiring.so i pulled off and car seems to drive fine but when stationary it occurs again im thinking a coil pack is on its way out but ive had 1 or 2 fail and they didnt show any signs they just let go.i have recently fitted a b5 tip could the extra air folw/an old maf cause these problems?? any pointers would be appreciated as no access to vcds

    Could be a few different things, have a look for any obvious split pipes also could be a dirty throttle body? Best to have it scanned with vcds. where abouts are you as there are plenty of vcds owners on here who are happy to help!
