Will 16.2 Ohm injectors work?
I had two stuck injectors after a cam swap and I bought these http://store.summitracing.com/partde...5&autoview=sku
injectors at Summit. I installed them and started the engine. It threw DTC 0200. I didn't think the 2.2 Ohm impedance difference would be a problem.

I stand corrected.
By the way Shoebox, I want to thank you for your tech page. I can't tell you how many times I referred to your site while working on my car. The pictures and drawings made sense out of what otherwise would have been a meaningless mess of wires and hoses.
THANK YOU!

The main thing you have to be concerned about is that they are "high impedance" injectors, which they are. The normal range for high impedance injectors is 11-16 ohms, but there should not be any harm in using a 16.2 ohm injector. It just means the current draw through the injector driver in the PCM will be lower, which isn't going to hurt the driver. If the injector manufacturer chose to wind them at 16.2 ohms resistans, he must have determined that it would put sufficient energy into the coil to open the injector reliably.

The code sets if the voltage on the injector circuit drops close to "0". The resistance of the injector wouldn't cause that problem. A near-0 voltage would result from a short in the circuit, not high resistance.
