91 240sx ka24de

Okay, basically my car has been randomly running like crap for some time now.

Sometimes it runs absolutely fine and then other times it sputters,wants to stall at lights, cat starts to smell. sometimes i can smell gas under the hood (not leaking) I just tested the resistance of my injectors and I got 12,12,12,16 (back to front) would the 16 indicate that my front injector is bad?

Also, any other ideas as to what is causing this would be much appreciated

Oh and spark plugs were replaced in October

ThanksSean

I am pretty sure its bad if all the other ones are the same. Did you check the service manual for there normal resistance ratings?

IIRC, the resistance should be 11ohms.

Would being off by 1 ohm make a difference?

1 ohm could be the difference in multimeters...

clean all the connections, re-seat the plug connectors, then measure again. If you get the same results, I'd say the one with the higher resistance is failing.
