All of a sudden today my car ('90 talon tsi) started running like crap. It idles well but
at speed (2000-3000) rpms it misses occasionally. Also the turbo seems to be almost non-functional. I get no boost at all untill about 3k rpms but It never goes above 7 on the boost guage and I have to get to about 4500 rpms to even get that? Any suggestions?
