Re: Code 31 - Camshaft Sensor
Are the Accel 150821 injectors still the choice for replacements? From the research I've done, they appear to be direct replacements.

Check out this link. It is Marc Haibeck's take on doing some of the diagnostic operations that may be of use to you.

Re: Code 31 - Camshaft Sensor
Actually got a referral to the Fuel Injector Connection today and ordered a set of the Delphi replacement injectors. They are supposedly prepped for direct installation, flow tested and matched. They also sell the plenum gasket set with it.
Anybody had experience with these? Also, any nice step by step instructions for injector replacement and plenum R&R out there?

Re: Code 31 - Camshaft Sensor
Charlie, a large number of the Z brothers have used Jon's new s/s replacement injectors with great results. Good parts at a fair price, and the gaskets are a very high grade of reproduction gasket from Jerry's gaskets.com.... it's one stop injector r&r shopping at it's best. Great choice!
Tom Over at Marc's site I believe there is a step by step on the injectors. I know over at PNWZR1.com there is a "how to" write up, over at corvetteactioncenter.com I also believe there is a thread. Also, I think in Cliff's "Solutions" section here there maybe a step by step. If after checking all of these you still have Q's post up.

Re: Code 31 - Camshaft Sensor
Ok guys, the saga of the poor running Z continues. Got a new set of Delphi SS injectors installed, started it, and it still acts like it's running on 5 or 6 cylinders. Ohmed out the new injectors and they all check fine. Checked fuel pressure - good. ECM seems to be communicating with the scanner fine. Only theory at this point is the plugs may be fouled from the injector failures. Any other thoughts or suggestions?

Re: Code 31 - Camshaft Sensor
Charlie, hummmm now this is going to be something stupid, ya just know it! Trouble is we have to noodle the answer. I think you should start a thread of your own on this subject so your issue don't get lost in Patton's stuff. Just give a synopsis of what was done and the symptoms.
I'll go get my FSM and start reading and check back at coffee break or lunch and see if I can contribute something useful. Fear not! No Z left behind! I'd check the plugs for sure though. Tom
