Hi Scotty, I have a 91 Audi 200 turbo I bought from an older gentleman that didn't use it much and has been sitting in his garage for about 10 years; the car runs pretty smooth and I kind'a like it but it doesn't start as quick as it's suppose to (it cranks about 5 to 7 seconds before it starts); I've replaced the check valve on the fuel pump but didn't help; I suspect it's probably one or more injectors that don't spray the fuel properly; should I try an injector cleaner product, or is there an easy way to check them out somehow, or what should I do to fix this starting problem that's bothering me please ?
Thank you
