injector cleaning

[Decsi Miklos <MDecsi@pgsm.hu>]

Hello,

 My '83 Audi 80 Q (I5 engine, K-Jettronic) has some problems. It hasn't been
accelerating well under 2500 rpms for 2 days now. 

 Gas is very "dirty" here in Hungary, so I suspect my injection system got
dirty too. Maybe it isn't the problem, but if I clean this that won't do any
harm.

 There can be bought different injector celaner fluids here. You just have
to add them to the gas and they will do their job.

 Has anyone tried them (I am sure some of you did) before? What to look for
when buying a thing? Are there better ones or worse ones? There is one
brand, called Wynn's (I think) which sound like it is an American one. Do
you know this brand?Is it good?

 Thank for all your help.
