I bought a set of rebuilt injectors from FIC. It should be here in a few days.

This was a good read. No matter what the maintenance history is the injectors appear to degrade over time. I want the car to feel like the first time I ever driven a C4 Corvette which would be 1986 or 87.

I was thinking the same thing. I will test and change it tonight and see what happens.

Ha! Thanks LT4man. I spoke to Jon yesterday. According to Jon, since all or most gasoline is blended on ethanol, the injectors should be replaced on general principle. He said something about the ethanol degrades the wiring in injectors. I had a 1969 442 and had a similar issue with a...

Ran a test on each injector Driver side front to back (left to right) (12.6 ohm/10.64v 12.5 ohm/10.62v) (12.4 ohm/10.83v 12.6 ohm/10.6v) Passenger rear to back (left to right) (10.7v/12.6 ohm 10.7v/12.6 ohm) (10.7v/12.6 ohm 10.7/12.8 ohm) Bold face is the one with worn electrode.

s I would like to test each injector before installing a new set. I didn't mention this Corvette has 120k on it. After doing various reading around the net not to mention the symptons its pointing a fuel injector problem.

After I made my initial post I started putzing around in the garage. It looks like cylinder 8 or the last/closest plug to the cowl was bad. I did put a couple of pints of Sea Foam in the tank. I buy the cleaner by the gallons. Sea Foam | Products

Took it for a spin out of curiosity after cleaning the passenger side plugs and now the pinging\stumbling is more obvious. Plug was not necessarily melted but was definitely worn out. It actually ran a little better before cleaning.

Understood. Throwing parts at it ain't going to solve the problem. However at 18 years old it would hurt. I do see one plug on cylinder 8 that needs to be replaced. Looks like the central electrode burned down some and a tiny piece stuck to the ground side. Thanks for the advice. I'm looking...

Two weeks ago I finally purchased my first Corvette, a Admiral Blue 1994 Corvette LT1. I have been a die hard fan since the introduction of the C4 in 1984. After years of looking at Callaway and ZR-1 Corvettes, I decided that I needed to start somewhere. This will not be my last one but its a...
