Hey guys, i am having a serious issue with my 93 s13 with the KADE. A week or two ago i was driving and suddenly the engine lost power, feels like its about 50hp. The car shakes, no power and it cosumed a lot if fuel in a short time. It now smells like raw gas fumes are coming out of the exhaust.

I figured one cylinder wasnt working, so i pulled a plug wire one at a time to see if i could rule one out. Well cylinder #2 seemed to be the one. I put all new spark plugs and plug wires in thinking that would fix it and it did nothing. So then i start thinking it might be the injector, so test them all and the resistance on them are 13.5, 21, 50, 11. Surprisingly the one at 50 is cyl 3. #2 is 21.

So, my question is, how do i know what the resistance of the injectors should be, and is there any recommendations on other tests that i can do for the injectors?
Also, if someone thinks im on the wrong track, let me know, o rings maybe? I need to sell this car, so need to get it running right asap. Thanks

Check and replace your o rings is what I'd do.

The resistance of each injector should be roughly 11ohms on each one.

injector stuck/sticking? swap the injector from the misfiring cyl to another and see if it follows

Are you using the same injectors because that is a wide range of values?

Take the rail off.
Prime fuel system... Do any injectors drip?
Yes- Check/Replace o-rings
No- Put a paper towel under them and spin the motor.
Do they all fire the same?
Yes- Shouldnt have an issue
No- Replace problem injector

Factory resistance is 11-14 ohms I think. So either you're not measuring correctly or you have 2 bad injectors

Bad coolant temp sensor can cause super rich condition

Thanks for the suggestions. I will have to time to try them this week and i will report back my results.
