Default Injector/performance ?

I have a stock 89 Coupe 350 TPI. One injector reads 8 Ohms. The other seven 16+. How much of an impact will the one bad injector have on acceleration/performance? I have no frame of reference since the injector may have been spent when I purchased the car.

Huge impact on the '89 - one bad injector can drag down both banks - change them all. Get some ethenol compliant injectors installed ASAP.

The ones I got from FIC worked great. That's the only way to go as far as I'm concerned. Made a huge difference.

A new set of injectors that have been reconditioned and flow matched will make an immediate improvement in over performance.
You will be amazed and question why you hadn't made the investment a long time ago.

FIC will help you choose the right match for your engine and stand behind their product.
