Hello all.
Great site!
I recently had a code 45 set on the car (92 LT1) Rich o2 left side. and my AutoXray 6000 says I am running a little rich on the left bank. I did an injector leak down test on the car today and after 20 min. there was no leak down at all. Then I did a drop test on all of the injectors and they all dropped the same except #5. I couldn't get #5 to fire with the injector tester. I checked the resistance on all of them and got 13.2 Ohms on all but #5. I got 4.1 Ohms on #5. Obviously I have a problem with #5 injector but what I can't figure out yet is why I'm getting a rich code #45 on the left bank when my testing shows I have a problem with one injector NOT firing. Could the lack of resistance in the #5 be causing some sort of electrical glitch with the rest on that bank??? The 92 Vette is a Batch fire system, not sequential.
I'll likely change the #5 but anybody got any ideas???
Thanks for the help.

Ok. Since nobody wants to take a shot at the rich lean thing, could anybody recommend a set of quality replacement injectors? A replacement Multec from the dealer is $155.00 my cost, so I think if I can get a real good matched set it may be the way to go..
Thanks

Try sending out your injectors to www.cruzinperformance.com. They test and flow match all your injectors for less than the price of one new one.

 

Thanks for the reply.

I can buy 8 new matched Accel 24 lb. injectors for $229.95 at Summit. I've been on the phone all morning trying to sort this out and have spoken to several people. Most of them don't seem to have a clue what they're talking about. Any of the jobbers I call only sell Borg Warner or Delco and they are expensive!!! I thought there may be some people on this site that have tried some of the aftermarket injectors. The rebuilders and carb shops want about $35.00 each ($280.00 plus tax) to clean and check mine but if I can buy a new set for $230.00?? You know what Homer would say (Doh!)
Thanks for the help.
