Can anyone tell me the impedance ranges are for the stock injectors?

 

According to Google and this website too (with translate from French if necessary)

11.7 (10 to 12) ohms // 190cc

 

Okay so I tested the resistance of the 4 injectors. Starting from pass side to driver side they read 13.1...............13.2...........13.1............ . and 12.9............

Are they within spec?

 

Any particular reason you're worried about this? Keihin injectors almost never go bad. It's almost unheard of. The odds of all 4 being bad is just about non-existant.

 

I keep getting the same CEl code. O2 sensor slow response. Yes I replaced the O2 nsesor a few times and it still comes back. Also replaced exhaust system, full cat all the way back, due to old one rusting out. There are no leaks. I read somewhere that this slow response code can also come up due to faulty fuel injectors. My car has over 205k miles on original engine.

 

What is the OBD2 code? Is it for the primary or secondary O2 sensor?

If you reset the ECU, does the same code return?

The O2 sensor code can also be thrown by a poor connector in the O2 sensor or ECU connector.

 

P0133 Primary 02 slow response. I have checked the connections and wires around the 02 sensor but code still comes on. It will always activate at part throttle, and activates faster if the ac is running. When I say it activates, I mean if I connect the scan computer and turn the CEL off.

 

Unplug and replug the ECU connectors.
