So we all know there are a zillion threads on this forum where people have issues, we all chime in and suggest distributor is at fault, and then we never hear back on a resolution from OP. So what I've been trying to do is create a list of all threads where:
The rationale for keeping this list is to summarize the issues and confirmed cases for future posters who might have questions (much like the oil burner thread).
Some common trends from skimming distributor threads:
Primary coil:
Cold: 1.11-1.75 ohm
Hot: 1.31-2.05 ohm
Secondary coil:
Cold: 9.0-14.7 kohm
Hot: 11.4-18.4 kohm
Pickup coil:
Cold G+ and G-: 185-287 ohm
Hot G+ and G-: 250-325 ohm
Cold NE+ and NE-: 370-550 ohm
Hot NE+ and NE-: 475-650 ohm
Notice the usage of kohm vs ohm.
Here is the list:

Deeder's fix it list, now with long thread life™
Symptom: No-spark / no-start
Initial diagnosis: Happened right after piston soak
Resolution: New distributor fixed the issue.
any ideas? Car idles, but then dies when put into drive)
Symptom: Engine revs fine in neutral. Put into drive and it goes for a couple seconds then stumbles and dies.
Initial Diagnosis:May appear to be transmission-related problem.. but...
Resolution: Bad ignition coil (inside the distributor). Replaced it with a new one fixed the issue.
1st/2nd Gear Stumble
Symptom: a severe stumble when getting on it in first and second gear. hit third gear or better and the stumble is gone.
Initial diagnosis: replaced ignition rotor, cap, wires and plugs, fuel pump, sock, filter, injectors and regulator (intake and fuel rail thoroughly cleaned), map and tp sensors
Resolution: the new coil did the trick. 500+ mi since replacement and she's purring like my cat after devouring a fresh kill.
Engine performance issues on 95 Corolla DX
Symptom: car may begin to act weird, loose performance after driving for a while.
Initial diagnosis: replaced fuel pump, fuel filter, cleaned injection system. Then replaced MAP, TPS sensors, EGR valve and air filter. Cleaned throttle-body and IAC. Replaced rotor, cap, wires, and plugs. Replaced distributor with Duralast brand from Autozone, no fix. Finally replaced ignition coil and it made symptoms even worse.
Resolution: went to a local pick your car part salvage yard and acquired ignition coil from another 7th gen Corolla. Replaced it and so far my car runs great!
97 Corolla Died, Won't Start
Symptom: car started sputtering on way home from work. Next morning it wouldn't start.
Initial diagnosis: timing-belt broke? Skipped teeth? Fuel-pump doesn't turn on.
Resolution: Pulled junkyard distributor. Pulled the old one, put the new one in, cranked the engine and it started right up.
I know I know, another jerking/bucking thread, but maybe...
Symptom: Random buck around 65mph when trying to coast. It has slowly been getting worse, and happening anytime over 55mph now and really bad over 70. Like bucking almost moving engine. I have to keep almost a constant acceleration or let go of the gas all together when I'm on the highway.
Initial diagnosis: Ignition coil. Replaced with Autozone part. No difference or worse.
Resolution: Pulled junkyard ignition coil. Fixed issue.
1995 Prizm LSI running issues
Symptom: It would start but the car would hunt for the idle and rev up and down and then die. Even if you push on the gas it still wouldn't smooth out.
Initial diagnosis: "Thought for sure it was the ECU" ...."They told me the best they could tell it was either the MAP sensor or the ECU"
Resolution: Got a junkyard Denso distributor and that fixed the issue.
'95 with occasional misfires when accelerating
Symptom: About two months ago, it died on me on the way to work. I replaced the spark plugs, wires, distributor cap, rotor, and ignition coil, and it started back up. Except now it doesn't run smoothly at times. As it warms up, it misfires a lot while accelerating, I'm guessing around 1500-2000 RPM, but there's no misfire at much higher engine speeds, or at idle, or when it's cold.
Initial diagnosis: Swapping out the ignition coil for another one made no difference, as did swapping the distributor cap back. So now I'm thinking it's either the distributor itself, or the crankshaft position sensor. I measured the CPS (2kOhms exactly) and the pickup coil in the distributor (220 Ohms), and both appear to have normal readings.
Resolution: The first attempt at replacing the ignition coil was with an aftermarket coil. Swapping that out with an OEM ignition coil solved the issue
NOTE: This thread also serves as an excellent read-through for the amount of testing one can perform to diagnose the distributor. It's a highly recommended read.
Engine stalls at when at operating temperature then...
Symptom: I have a problem where the Car runs just fine but once its in the operating temperature range for a little bit, the car just stalls. It does leave behind a check engine code 14 tho but doesn't display while vehicle is running. When I wait about 5 minutes after it stalls, It will start right back up and not die at all even when I'm driving it around.
Initial diagnosis: I have replaced the following:
-Battery
-Alternator
-Timing Belt
-Fuel pump
-Fuel filter
-New Distributor assembly with cap (editor's note: Non-OEM distributor)
-ECM
-Spark plugs and wires
Resolution: Swapped distributors (editor's note: OEM distributor from junk yard) using the mark with Nail polish method, and the Car "IS NOT" Stalling.
Irishdad's journey:
Part 1: 95 Corolla 1.6L/4AFE ran fine, now no start
Part 2: 1995 Corolla crank/no start UPDATE
Part 3: 1995 Corolla crank/no start-Latest update
Part 4: 1995 Corolla Update and my THANKS!!!!
Symptom: We needed to run an errand, literally a block away (would have walked but it was over 100 degrees out) and the car turns over but doesn't start/catch.
Initial diagnosis: Multiple (see various threads)
Resolution: New distributor as well as fixing a mobile mechanic's incorrect timing belt install and timing adjustment.
HELP! I need your guy's help. My 93 1.6L won't...
Symptom: Car stalled when hot. Wouldn't start back up.
Initial diagnosis: Fuel injectors, distributor (replaced with aftermarket)
Resolution: New aftermarket distributor didn't fix issue. When replacing coil in distributor the issue got resolved.

Symptom: Original distributor died, was replaced with an aftermarket distributor (World Power Systems DST77417). After 30 days the engine started sputtering and then died.
Initial diagnosis: Spot on, thanks to this thread and all the users who contributed
Resolution: Had preemptively rebuilt old OEM distributor with new coil, cap, gaskets and rotor. Swapped that back in and the engine started running normally again.

Symptom: Stuttering Idle. Hesitation When Driving
Initial diagnosis: Original distributor was replaced with aftermarket due to oil leak. Aftermarket distributor was assumed good.
Resolution: Replaced aftermarket distributor with used junkyard distributor. Issue solved.
Distributor internals - coil is #8:
- OP listed symptoms/issues
- Distributor was suggested by other forum users as a root cause
- OP came back and confirmed putting a new distributor in fixed the issue.
The rationale for keeping this list is to summarize the issues and confirmed cases for future posters who might have questions (much like the oil burner thread).
Some common trends from skimming distributor threads:
- There is a reluctance to believe aftermarket/reman replacements can be bad right out of the box, yet it is commonly a pattern. On the other hand, there are also some threads where aftermarket/reman did seem to fix the issue, but it seems like a roll of the dice. EDIT: Here is an excellent explanation for why poorly manufactured aftermarket distributors fail out of the box: need 95 Corolla pinout diagram for ECM
- The transmission is frequently a suspect in the bucking/stuttering cases, yet it's the distributor ending up being a root cause.
Primary coil:
Cold: 1.11-1.75 ohm
Hot: 1.31-2.05 ohm
Secondary coil:
Cold: 9.0-14.7 kohm
Hot: 11.4-18.4 kohm
Pickup coil:
Cold G+ and G-: 185-287 ohm
Hot G+ and G-: 250-325 ohm
Cold NE+ and NE-: 370-550 ohm
Hot NE+ and NE-: 475-650 ohm

Apples555's 95 Corolla Thread
Rather than make an infinite number of threads about every tiny thing, it's probably best to collate everything into one so readers can understand the conversation in context like others have done here. Last week, I noticed a puff of steam from under the hood. Of course, the 3 year old radiator...
Initial diagnosis: Spot on, thanks to this thread and all the users who contributed
Resolution: Had preemptively rebuilt old OEM distributor with new coil, cap, gaskets and rotor. Swapped that back in and the engine started running normally again.

Studdering Idle. Hesitation When Driving
I have a 1993 Toyota Corolla with a low millage (JDM) engine (obd1) in it. I've replaced almost everything and it's sort of like a brand new engine. Many of the sensors I've replaced because I've been stabbing in the dark trying to figure out why the car keeps hesitating, cuts out, when being...
Initial diagnosis: Original distributor was replaced with aftermarket due to oil leak. Aftermarket distributor was assumed good.
Resolution: Replaced aftermarket distributor with used junkyard distributor. Issue solved.
