93z bad miss and stalls
I was checking connection and unpluged the intake air temperature sensor and the miss went away. I replaced the sensor and the car ran the same with the new iat installed drove the car the last few days with it unhooked and the car ran great ? Now it's stalling out after setting from 15 mins to 3 hrs it will restarted
I do get a code 23 which is IAT sensor low temperature because its unhooked no outher codes
Changed the coil , same, checked injectors 12.5 to 12.7. I thought I found two bad ones the first time I checked them they where 30.2 and 31.0 but after checking the rest and rechecking they checked 12.6 and 12.7 must of been my cheap meter unless they can change resistance (yea Right) last night while it was runing I moved and struck any thing under the hood from computer to wires no change in rpms I hooked up the iat and it stalled out and wouldn't restart with the iat hooked up or unhooked I went out today and it started right up ??????????????????????????????????
Thanks Rick

car stalling and wont start
How many miles on your car? How long have your plugs and wires been in(I would check that first),I have a 93z.I have 94,500 miles on it. Had a friend pull plugs and wires for me. Platinum tips were GONE, car could not hold spark anymore. He put in ngk tr-55 platinums, and MSD 8.5 wires and now throttle response is great,no miss,nice idle,better mpg.They may last a while longer than regular tr-55s. secondly you can clean your idle control valve on side of throttle body. I cleaned mine, you should of seen all the gunk pour out of it.This will help it with the idle.Tou can also clean out throttle body itself. Just some thoughts. Good luck. Pickerman
My plug gap must have been about 80 because my tips were gone on my plugs!!

If the IAT cost alot from the dealer/parts store/etc.
If you pay shipping I'll GIVE you my IAT of of the 93 in the sig. I have the stock one that I used until I got the 1LE elbow which came with an IAT already in it.
Shipping couldn't be too bad
