Bad Injector????
DataMaster is showing KR at 2000 to 2200 RPM.
Guys I JUST came in from another brainstorm session with the Vette.
I have 7 injectors that read 16.9 to 17.1 ohms.
Got ONE that is 10.9 ohms.
That one is on cyl. 6 about as close to the KS as you can get.
I've listened to them all with a stethoscope and they all sound alike. I can hear them pulsating.
Could this one odd injector be doing something to the mixture on that one cylinder and cause all this grief????????? (Knock retard at 2000 to 2200 rpm)
On my datalogging on the way home from work I'm still getting some KR at 2000 to 2200. Mostly right at 2050 RPM at medium Kpa. When I go PAST this point (higher Kpa) the knock retard goes away and the engine takes on off and runs good.
I think I've got some sort of mechanical problem and it may not be mixture/spark related.
What do you guys think? Particulary about the injector.
EDIT:
BTW: I just pulled the plug for 6 and it looks ok...nothing out of the ordinary. White insulator..... a little sooty deposit on the base of the plug shell. Looks like all the others.

Re: Bad Injector???? (VetNutJim)
I posted this over here because there's Scan & Tune gets so few responses.
Hmmmmmm I must be the first person to EVER encounter this problem.
