What do I need to get to scan my car? Is it the vag-com? Im not sure being so old. Its an 89 audi 80 quattro 2.3l. It starts up but as soon as it starts to warm up it basically just runs like crap. It misses at low idle, has a hard time idling and it wont rev up unless you hold it to the rugs. Completely undriveable. Does have 263,000 miles but nearly all highway driving. Ran good until one day it decided to give me grief. Any suggestions on what I should do with it would be greatly appreciated
