A good friend has a 1991 Z and it has a slight miss in it. He has been told that the injectors for this car were not designed for Gas that contained ethonol and they likely need replaced. We're looking for advice on what injectors to buy for the replacement.
Thank you

You will also require plenum gaskets and o rings.
All available at Jerry's.

If it has the original injectors they will need to be replaced. But first I would check the plugs. Pull the wires and make sure they all are firing. How many miles does this car have on it? I had a mis in my first 91 at around 70,000 miles. When I checked the plugs I found that cylinders 1 and 3 were not firing. Turned out the coil for those cylinders was bad. The car has four coils and the cylinders that weren't firing shared the same coil. I replaced all the coils and the plug wires while in there. You have to pull the plenum to do the injectors you might as well check things out while your in there.
