Default 1990 Fuel Injectors Bad?

1990 Corvette with 22,000 original miles and the fuel injectors are bad. The car has a miss and when it is up to operating temp it runs bad. What should I replace them with?

we recommend the Bosch 3.. They are 100% alcohol compliant and work great..They are 169 for the set. If you would like to keep it stock looking we have new Delphi's also that are stainless steel and have the same case as the multec. These are 349 for the set. The Bosch have a 3 yr warranty.

The original Multecs in the '90 werent very good and prone to failure. With only 22K miles, it sounds like they may have sat dry for a period of time, also not good for injectors.

I would go with what Jon suggests. He knows injectors and is a gentleman to deal with to boot!

Jon is to be trusted, which is a rare commodity these days. Follow his lead. I put them in my 90 and it runs like new.
