Hey, Good morning Yota Techers,
I am not exactly sure that this is related or belongs in my current thread but easier to keep it all in one place maybe.
Monday morning I went to start my truck and it fired up right away but it was not idling right at all, it was jumping all around and staying closer to 4-500 RPMs, but we all know that a cold engine should be idling at closer 1-1200 RPMs. I am afraid that my cold starting issue is returning with the change in the weather, however, I opened the hood while it was running rough when I first started it and I did notice something I had not heard before. There was a clicking/ticking sound coming from what sounded like the inside of the distributor, I am very concerned about that, I know that a bad distributor can make your engine run pretty bad, with misfires and what not.
Is it possible that my distributor is going bad and its symptoms are only really showing in the colder weather?
Thanks everyone!

open up your distributor and check condition.

Sure. Localize that sound. You can get a fancy stethoscope for cheap https://www.harborfreight.com/mechan...ope-63296.html , but for something as accessible as the distributor the tube from inside a roll of paper towels works really well.
I used that method (before I got the fancy stethoscope) when my GF said her car sounded like it was chewing up aluminum cans. I found the sound was coming from the distributor (bad bearings), and replacing the distributor solved the problem.

Thanks, RAD, I always appreciate your input on everything.
From the outside, the distributor looks brand new but I know that this can be deceiving, gonna check that when I get home from work today.

Good morning Yotaheads,
I just wanted to reach out and give an update here on this.
I checked for air and vacuum leaks and there was none that I could find, inspecting the distributor and it appeared to be in good order so I made an appointment for after the Thanksgiving holiday to take it into my mechanic and let him have a look.
This morning I had to leave for work before the sun was up and when I fired my truck up the issue was back again, fired right up and the idle was really low and surging a bit. I decided to open the hood and see if I could hear that electrical clicking sound this time, sure enough, I did hear the click and what I noticed this time was my Ah Ha moment! Since it was dark outside I could clearly see a small electrical arc between where one of the wires connects to the distributor and the power steering pump. I tried to just make sure the connections were tight with all the plugs but it was still arcing and stumbling around.
I would say that I am almost positive this is the issue, that will explain the little surges at around 2-3000 RPM's while driving also, it's having a little misfire most likely because of this current draw.
I am going to let my regular mechanic check it out since he is a family friend who I trust and I know he won't lead me to believe it needs more than it does, but I am also thinking I will just get a new cap, rotor and plug set since these items most likely need to be replaced anyway.
Thanks everyone for all of the tips and tricks!!
I will update again once I have a chance to get this further.

Curious... which wire would that be? Ignition wire? Could have a crack in the insulation? A picture paints a thousand words and could help you save $$ if we saw it.

I will try to maybe get a pic of it during the light today as well, but I only noticed this finally today because of it being so dark outside.
Thanks to everyone for there help as usual!

If your ignition wire is arcing through the insulation to ground then that means you have no or every weak spark to cylinder 2. That could definitely cause your running and starting issue.
always fix known issues prior to others.
at this point i would say a good set of oem toyota ignition wires is in order, however a picture of said wire would confirm for us giving advice.
do yourself a favor and do not buy parts store wires. Get toyota

Hey Everyone,
I was able to capture the arc in a photo, I went ahead and ordered some new plugs, wires, cap, and rotor. I am thinking that should do the trick. Connection at wire #2 arching out to the power steering pump.

WOW! That's a nice clear picture! Inspecting those individual parts may have saved you some money, but replacing those 30 or so year-old parts makes sense.

Thanks RAD, it just kept snapping shots I figured I would capture the arc in one of them.
BAD NEWS FOLKS, my 4Runner was STOLEN from my home last night most likely sometime around 3am-6am.
Stolen from Sacramento, CA.

Curious to know what the resistance is on that plug wire and what the spark plug looks like. Something must make it want to jump a half inch instead of the plug gap.
Nice "snow runner' avatar by the way!
