Default Cleaning Non-Multec Injectors??

Anyone tried having their non-Multec injectors cleaned?

How'd it turn out, did you scan before / after BLM's? Who did you use?

I'm thinking about giving it a shot with the Rochester injectors from an '88.

Thanks

Rob

I didn't scan it since I make it a habit to send them off every few years for cleaning. I would imagine it makes a difference when the injectors are all flowing at different rates with different spray patterns. I send them off to FIC for cleaning and testing. Usually I see the before volumes erratic and after more uniform.

Did the 88 have Rochester injectors or how did you verify that? I thought they were used till early 90s?

The injectors have a Rochester logo and part number 5235302.

I talked to Jon at FIC today and will send them off.

You send yours out every few years? They change that quickly? Gotta burn the gunk out of that motor every once and a while!
